Semi Renky

The Semi Renky is a Japanese 4.5×6 camera that was made by Rengo Koki between 1939 and 1941. It looks like the Olympic.

There were at least two versions:

• Semi Renky with bakelite body, 25-50-100-150-B-T shutter, f/4.5 lens and accessory shoe, RengoKoki and Tokyo on the helical ring, Semi Renky on the shutter plate and Semi Renky in capital letters on a body plate (similar to the plate marked The Olympic Camera Workson the Olympic cameras), illustrated here at Japan Family Camera
• New Semi Renky with a different metal body, same shutter, Tenobar Anastigmat 75/4.5 lens
  • marked RengoKoki (and Tokyo?) on the helical ring, New Renky on the shutter plate, no body plate (illustrated in McKeown)
  • marked New Semi Renky and Rengo Koki Tokyo? on the helical ring, Semi Renky on the shutter plate, no body plate (observed at ebay auction)
