Template:127 Japan The Riken Chukon Ref was a 3x4cm format camera released around 1940. It was a pseudo TLR: its shape imitated a twin lens reflex but it was fixfocus and the finder was nothing more than a big brilliant finder. It had a black bakelite body, a Chukon Anastigmat 50/6.3 3-element lens and a T-B-25-50-75-100 shutter marked Chukon Ref and R.K.K. for Riken Kōgaku Kōgyō (Riken Optical Industries). It is said at Ricoh's corporate site that it was only sold by Riken and made by another company. There is a reference on this page at tlr-cameras.com to a 1939 fixed focus pseudo TLR made by a company called Prince Camera Works, it was possibly the same as the Chukon Ref.
Most of the info above comes from Ricoh's corporate site, very few other information has been found.
Note: The name Chūkon (忠魂) means "faithful spirit" and can have the sense of "loyal dead" or "war dead". Riken used such weird "patriotic" names during the war.
