For the postwar company of the same name, see Walz.
The Walz was loosely inspired by the Foth Derby. It has a metal body with round edges. The front standard is metal coloured and is mounted on a pair of scissor struts placed on each side. The advance knob is at the top right, as seen by the photographer, and there is a smaller film flange at the top left. The tubular optical finder is attached to the top plate by a hinge, to gain a few millimetres in height when closed (same system as on the Derby). There is a small button placed to the right of the finder; it looks like a body release but is simply used to open the front standard. The back is hinged to the right. Film advance is controlled via one or several red windows, protected by cover(s). The exposure chamber has guide rolls on both sides, to enhance film flatness. The name Walz is inscribed at the bottom of the front plate and is embossed in the leather covering at the front of the camera. The dimensions are 9×7×3cm.
The lens is a fixed-focus Walz Anastigmat f/4.5, whose focal length is unknown (it is probably 50mm). It is engraved Lens Walz Anastigmat F4.5 N°xxx. (Early advertising pictures do not show a serial number, perhaps because they were retouched.) The shutter is placed behind the front plate. It gives 25, 50, 100, B, T speeds selected by a dial placed above the lens. This dial is engraved Walz. The aperture is controlled by an index at the bottom, moving on a crescent-shaped scale. The everset shutter is tripped by a lever attached to the front plate.

The Walz was first advertised in October 1936, and was featured as a new product in the November 1936 issue of Asahi Camera, reproduced above. In the document, the camera is called "Walz A Pocket Camera" (ワルツAポケットカメラ), and the price is given as ¥24.

|Advertisements for the Walz in Asahi Camera. (Image rights)|
The advertisements placed in Asahi Camera from October 1936 to April 1937 are reproduced above. In most of these, the camera was touted as suited "for the gentlemen's pockets and for the ladies' handbags" ("殿方のポケットに・御婦人のハンドバッグに"), and with appropriate pictures. All the documents give the same price of ¥24, and were ostensibly placed by "Walz Camera Works" (ワルツ・カメラ・ウオークス).
Later advertisements dated June 1937 say that the camera was "made by Walz Works" (ワルツウオークス製) and mention the company Nihon Shōkai, certainly as the distributor. The camera is listed at an unchanged price, an ever-ready case is mentioned for ¥3.50, and another accessory for ¥3.00 (perhaps a hood with filter holder).
It is doubtful that Walz Works or Walz Camera Works was the name of an actual company. It seems that this kind of names was only used for advertising purposes and hides the true name of the manufacturing company (see Camera Works). In the case of the Walz, various sources say that the actual maker was Okada Kōgaku. The brand name Walz was certainly owned by the distributor Nihon Shōkai, which was surely a predecessor to the postwar Walz camera manufacturer.
