Geltoflex
The Toakoki Geltoflex was a 6x6 TLR, made by Toa Optical Works. Two completely different versions have been observed. Both had knob advance with a red window in the back.
The first, probably older, version had external coupling of the taking and viewing lens, with a focusing lever on the taking lens. Speed and aperture settings were around the taking lens. The viewing lens was an unnumbered Grimmel Viewer 80/3.5 and the taking lens was a numbered Grimmel 80/3.5. Both had a red C. marking, presumably for "Coated". The shutter is B-1-unknown. The release button was at the bottom left of the front plate, at the bottom right was the sync post. The red window was round, covered by a sliding plate, and the hood incorporated a big loupe hinged at the back.
The second, probably later, version had two wheels for speed and aperture setting, like the Rolleiflex. The viewing and taking lens were mounted on a moving front plate for focus, the focusing command itself is unknown. Both the viewing and taking lens were numbered Grimmel 80/3.5, with C. marking. The shutter was a GKK B-1-200. The red window was rectangular with a sliding cover, the hood incorporated a sports finder and a loupe hinged at the front.
