The Proud plate folder was advertised in the 10 May 1934 issue of Nihon Shashin Kōgyō Tsūshin. The picture shows a regular plate folder, with a focusing wheel on the photographer's right, a brilliant finder, a wireframe finder, and vertical movements driven by a knob at the top of the right-hand branch of the front standard. The advertisement mentions a Lausar 10.5cm f/4.5 lens, and says that the price range went from ¥38 to ¥85.
The following combinations were reportedly available on the Proud plate folder:
- Radionar f/4.5 lens by Schneider, Vario shutter;
- Lausar f/4.5 lens by Tomioka, Rulex shutter;
- Lausar f/4.5 lens, Compur shutter (¥86 in 1934);
- Corygon f/4.5 lens by Friedrich, Compur shutter (¥85 in 1934).
A metal plate folder, apparently in 6.5×9cm format, has been observed with a film pack holder sporting the Proud logo. Its identification with a Proud plate folder is probable but not certain. The camera has a brilliant finder, a wireframe finder, a focusing wheel on the photographer's right and a distance scale on the left, but no visible movement ability. The folding bed release and the leather handle are atop the body. This particular example has a Rulex shutter by Neumann & Heilemann giving 1–200, B, T speeds, and a Corygon 10.5cm f/4.5 lens.
