There is also a Frank, six (cursive), MODEL 1950 that exists that is not yet mentioned in this post.  We are in posession of this model - that includes case, an additional view finder attachment (?) w/case, which lists distance in feet from 3 - 100,  and Roxy flash attachment and case - including a bulb inclusive of unbroken/unburned fillament.  TK stamped lens, 2 window sliders in back, flat film advancer with arrow - so appears to have the early features of the Frank, six - as described in this entry.  Frank logos on both sides of case are in all capital letters. There does not appear to be a serial #, just MODEL 1950 engraved on top. Anyone interested?  69.29.252.88 13:02, June 22, 2014 (UTC)R Stasiewicz
