The Frank Six (フランクシックス) is a series of Japanese 6×6 folding cameras produced from 1950 to 1954 by Tōsei Kōki. At the very beginning, the camera was also sold as the Beauty Six (ビューティシックス) by Taiyōdō Kōki. The Sanon Six (サノンシックス), Muse Six (ミューズシックス) and Liner Six are later rebadged Frank Six models.

The single-format Frank Six and Beauty Six (1950)[]

Description[]

The single-format Frank Six and Beauty Six have nothing in common with the later Beauty Six released in 1953. They are horizontal folders, with three-part folding struts inspired by the Ikonta. There is a T.K logo on the folding struts, certainly for Tōsei Kōki — it would stay on all the later Frank Six models. The top and bottom plates are chrome finished. The shape and layout of the top plate are similar to the early models of the Olympus Chrome Six. There is a tubular optical finder in the middle, whose rear has a conical torpedo shape. The body release is on the right and the folding bed release is on the left, in front of the accessory shoe which is attached by a single large screw. The advance knob is at the left end; it is quite high and has a conical base. There is a decorative film flange on the right end. The name is engraved in the top plate, in front of the shutter release, either as Frank.six in lowercase letters or as Beauty six in cursive letters. The body serial number is engraved just below.

The back is removed together with the bottom plate for film loading. It is locked in place by a rotating button in the middle of the bottom plate, with a red dot and an arrow indicating the opening direction. There are plain metal plates at both ends of the body, acting as a light seal for the removable back. The camera is single format, taking 6×6cm pictures only. The back has a single red window, protected by a horizontally sliding cover moving under an unusually long metal part, with a diamond-shaped frame for the window itself.

The lens standard has a plain round top and does not have the typical self-timer linkage of the Frank Six. The lens is a front-cell focusing 75mm f/3.5, the shutter gives B, 1–200 speeds, has a self-timer and is synchronized via a single pin at the top.[1]

Early documents on the Beauty Six[]

The earliest documents known so far are for the Beauty Six, advertised from July to November 1950 and featured in the October 1950 issue of Ars Camera.[2] The September advertisement in the same magazine shows a picture of the camera, and mentions a Seriter 75/3.5 lens, B, 1–200 speeds shutter speeds, a self-timer and flash synchronization.[3] The only company name given in the document is Taiyōdō Kōki.

Surviving examples[]

The single-format Frank Six pictured above has body no.1563, and is the only such camera observed so far. Its folding bed release is close to the advance knob, further to the left than on any other camera of the family. It has etched metal plates on the side, with the name FRANK in relief capital letters. The shutter is identified by the name TKS in double struck style at the bottom of the rim. It is synchronized via a single pin at the top. Its black front face also has an unusual SEMIX marking at the top, certainly Tōsei's T.K logo on the right, and perhaps another marking at the bottom. The lens is an S.O.W. Anastigmat 75mm f/3.5.

The same FRANK markings in capital letters have been observed on another example, pictured in this page at medfmt. It has a silver front standard with no logo, and it is not known if it has one or two red windows.

Two surviving examples of the 1950 Beauty Six have been observed so far, with body no.1611 and no.1736, later than those of the above Frank Six.[4] Their folding bed release is at the same position as on the later regular Frank Six. They both have a Seriter Anastigmat lens.

The camera no.1611 pictured in this page comes with its original case, in red and blue colours, inscribed Beauty SIX and T.K.K. The latter initials were used by Taiyōdō Kōki on later Beauty models, and certainly don't correspond to Tōsei Kōki. The same example has a TKS shutter, inscribed T.K.S. in double struck style at the base of the speed rim, certainly made by Tōsei Kōki. Its shutter plate is black with one metal stripe on each side, and has FRANK at the top and NEW PARAGON at the bottom. The brand name Frank was probably the property of Tōsei Kōki, and would later become the name of the camera itself. The words NEW PARAGON are also found on some examples of the postwar Gelto; their meaning is unknown.

The regular Frank Six[]

The regular Frank Six models are called Frank Six Model 1951, Frank Six Model 1952 and Frank Six Model I, according to the markings on the camera itself.

Description[]

The regular Frank Six are dual format cameras, and can take 6×6cm or 4.5×6cm format pictures when using an internal mask. The back contains two red windows, one for each format, protected by a cover horizontally sliding under a black plate. These black plates are engraved 4.5 X 6 and 6 X 6 to indicate the picture format. Two red lines in the viewfinder delineate the field of view for 4.5×6cm pictures.

The lens standard has protruding corners, one of them having a round lever actuating the self-timer.[5] The rear of the tubular finder and the shutter release differ from that of the Beauty Six. The accessory shoe is attached by three small screws. Red O and L indications (for Open and Lock) were added to the back opening button at some time.

The name Frank six is engraved in the top plate in cursive letters. The model name MODEL 1951, MODEL 1952 or MODEL–I– is engraved just below, in capital letters. The analysis of the serial numbers of the Seriter lens indicates that the Model 1951 and Model 1952 predate the Model I.[6]

All the regular Frank Six have a TKS shutter, with B, 1–200 speeds, a self-timer and a synch pin at the bottom right; the name TKS is engraved at the bottom of the speed rim. All the cameras have a front-cell focusing lens: a few examples of the Model 1951 have a Nomular 75mm f/3.2,[7] whereas the other have a Seriter. It is engraved C SERITER Anastigmat on the early examples and SERITER Anastigmat on the late ones (SERITER is written in red in all cases). Nearly all of them are 75mm f/3.5 but some might have 80mm focal length.[8]

Evolution[]

Very early examples of the dual-format Frank Six might still have the FRANK marking in capital letters at both ends of the camera.[9]

The regular examples have the name Frank in cursive style on the endplates, instead of capital letters. The same T.K logo as engraved on the folding struts also appears on the corner of the lens standard opposite the self-timer.

The engraving on the speed rim changed at some time, around the switch from Model 1951 to Model 1952: it was altered from T.K.S. in double struck style to TKS in regular capital letters. The only Model 1952 example observed so far has the latter engraving style, and the words Tōsei.O.W 1952 embossed in the back leather (Tōsei.O.W is underlined and probably stands for Tōsei Optical Works).[10]

On the Model 1951 and Model 1952 examples, the shutter plate has a black stripe and is inscribed FRANK at the bottom. Around the switch to Model I, a pattern of black and white triangles appeared for some time, with a TOSEI marking at the bottom.[11] It was replaced again by a thicker black stripe with a black diamond at the top and the same TOSEI marking at the bottom.

Various detail changes occurred at some point, after the transition from Model 1951 to Model I. On the early cameras, the lens standard is chrome with a black logo, there is no logo on the folding bed and the advance knob has a flat metal top with an arrow indicating the winding direction. On the late cameras, the lens standard is black with a white logo, there is a T.K logo embossed in the leather of the folding bed and the advance knob has a round leather patch at the top and no arrow.

At least some Model I cameras have Tōsei.O.W 1953 embossed in the back leather, the same as the embossing of the Model 1952 example. (This embossing is perhaps present on all the Model I cameras but this is unconfirmed.) One example of the Model I with chrome lens standard is known with the year 1953 vertically stamped in the leather of the folding bed, where the examples with black lens standard have the T.K logo.[12]

Commercial life[]

The camera was advertised as the Frank Six from November 1950, and was featured under that name in the February 1951 issue of Asahi Camera.[13] The first Frank Six model was presumably the Model 1951, followed by the Model 1952 in late 1951 or early 1952, then by the Model I. An advertisement dated May 1952[14] by Million Shōkai offered the Frank Six with Seriter lens for ¥10,000. The advertisement contains typos: the Frank Six is called "Flank Six" and the Semi Frank is called "Semi Flank". In the advertising picture, the advance knob has a flat metal top, the lens standard is chrome and the shutter plate is of the first type. An advertisement dated December 1952[15] shows the second type of shutter plate, with the triangle pattern.

The Sanon Six and Sanon Six II[]

The Sanon Six is a name variant of the Frank Six, distributed by Takasago Shōkai. The original Sanon Six was featured in the March 1953 issue of Ars Camera, with a Chibanon or Chibanone (チバノン) 80/3.5 lens and a TKS shutter.[16] The shutter is said to have a basic self-timer, perhaps consisting of a hole for a needle and thread: the shutter is released when the thread is pulled.[17] No picture of this model has been observed so far, and this version of the TKS shutter is otherwise unknown.

The Sanon Six II was offered for ¥8,500 in an advertisement dated June 1953.[18] The camera is identical to the late Frank Six Model I, with a black lens standard and a white T.K logo. It merely differs by the name Sanon–6 MODEL–II– engraved at the top. In the advertisement, the lens is perhaps called Chibar (チバー) and the shutter is a TKS with the late type of front plate, inscribed SANON at the bottom. The camera pictured above has a plain Seriter Anastigmat and a late TKS shutter, whose bottom marking is unclear.

The Sanon Six III and Muse Six[]

The Sanon Six III[]

The Sanon Six III has a top housing containing the eye-level viewfinder, slightly offset to the right as seen by the photographer. The accessory shoe is above the top housing, to the left of the viewfinder. The advance knob is quite similar to the knob of the Frank Six I, and there is a decorative film flange at the right end. The back is hinged to the right. The lens standard is black with a T.K logo. The camera's overall aspect is quite similar to the Frank Six IV, except for the absence of the brilliant finder.

The Sanon Six III was offered for ¥9,800 in an advertisement by Takasago Shōkai dated July 1953,[19] with a Tri-Lausar 8cm f/3.5 lens by Tomioka and a TKS shutter. Only one surviving example has been observed so far.[20]

The Muse Six[]

The Muse Six was advertised from August to October 1954 by the distributor Shinkō Shōji.[21] It is similar to the Sanon Six III, but has a Muse 80/3.5 lens and a TKS shutter only giving B, 10–200 speeds. It seems that the T.K logo has disappeared from the lens standard. The Muse Six was priced at ¥6,800,[22] perhaps to clear the stocks. No surviving example has been observed so far.

The Frank Six II and III[]

Almost nothing is known of the Frank Six II and III. One of these two models was probably similar to the Sanon Six III.

Lewis briefly mentions the Frank Six II as released in 1951 and the Frank Six III as released in 1952.[23] It is said that the Frank Six III was featured in a February 1953 column of Ars Camera.[24] An advertisement dated August 1953[25] lists the models I, II, III, IV and V, with no further detail. A camera has been offered at an online auction as a "Frank Six Model II", but no photograph was provided to confirm this.

The Frank Six IV and Liner Six[]

The Frank Six IV[]

The Frank Six IV has a top housing containing an eye level finder offset to the right and a waist level optical finder offset to the left. The accessory shoe is at the right end of the top plate, and the shutter release and folding bed release are located as on the Model I. The advance knob has a different shape, with a round leather patch at the top and an arrow indicating the winding direction. The back is hinged to the right and contains two red windows, similar to the red windows of the Model I.

The top housing is engraved Frank.six in cursive style and MODEL–IV– in red capital letters. The lens standard is black with a white T.K logo. The company name Tōsei.O.W is embossed in the leather of the back, under the red windows, and the T.K logo is embossed in the leather of the folding bed.

The shutter is a TKS (B, 1–200, self-timer), similar to the shutter of the Model I with the last type of shutter plate. The synch post consists of a single pin, an ASA bayonet or a PC socket.

The lens is a Tosei Anastigmat 80mm f/3.5 on most examples, sometimes with a red C engraving.[26] There are variations in the shape and colour of the lens bezel (silver or black). One example is known with a Tri-Lausar 8cm f/3.5 lens by Tomioka.[27]

The Frank Six IV was pictured in the August 1953 advertisement cited above,[28] where the lens was given as a Tosei 80/3.5 and the shutter as a TKS. The camera was offered for ¥9,800 with the same features in advertisements dated January and April 1954.[29] The model name is given as "Frank Six VI" in April 1954, perhaps by mistake.

The Liner Six[]

The Liner Six is a name variant of the Frank Six IV. The name Liner Six is engraved above the top housing, together with initials perhaps reading TSK, KSK or RSK.

One example has been observed with the usual TKS shutter and a Liner Anastigmat 80mm f/3.5 lens.[30] Another example is pictured in Sugiyama with a Rapidex shutter (T, B, 1–300) and a Lausar 7.5cm f/3.5 lens by Tomioka.[31] This lens and shutter equipment is certainly not original and probably comes from a wartime Semi Sport.

The Frank Six V[]

The Frank Six V is a rangefinder model, with a completely different top housing. The main body is similar to the Frank Six IV. The range- and viewfinder are combined in a single eyepiece, offset to the right as seen by the photographer. The rangefinder is certainly uncoupled but the position of the setting wheel is unknown. There is a sliding button at the front of the top housing, certainly moving a mask for 4.5×6cm pictures in and out of the finder frame. The shutter release and folding bed release are the same as on the model IV. The advance knob is the same too, except for the shape of the arrow. There is a film reminder at the right end of the top plate. The accessory shoe is in the middle, above the round rangefinder window. The lens standard is black with a white logo.

The name Frank–Six V.R (with an "R" surely for Rangefinder) is engraved above the viewfinder, together with the serial number and the company name TOSEI.KOKI CO, LTD. The T.K logo is also engraved in front of the accessory shoe.

Only one actual example has been observed so far. The shutter is certainly a TKS with a PC synch post, and the lens is a Tosei Anastigmat 80mm f/3.5. It has depth-of-field indications on a black background around the lens.

The Frank Six V was offered for ¥9,800 in the advertisements dated January and April 1954 cited above, with Tosei 80/3.5 lens and TKS shutter.[32]
