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 unkonwn. 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.
