This camera has a rimset Picco shutter with B, 25, 50 and 100 speeds.  The lens is a focusing Fuji-ko f/4.5 50mm Anastigmat Terionar that could be stopped down to f/32.

The camera shown here is complete and original with Fuji Kogaku appearing on each folding arm.  The bellows are intact and (amazingly) light tight although I have not used the camera.

This ad accompanied the camera when it was found several years ago and is believed to date from 1940.  As can be seen, several variations were available, this particular model cost 32 Yen.  According to Fujimura, camera production fell precipitously after 1941 and taxes on cameras was raised to 80% in wartime Japan.
