This is an automatic 2 leaf shutter unit with a multi-coated lens assembly made for a camera. Has a mounted multi-element coated lens assembly with a 55mm focal length. Clear lens diameter is 12mm. Complete with 1 solenoid (6.3V 10uF), 2 cadmium sulfide photo electric light sensor that determines the exposure and tells the solenoids when to open and close and hence the shutter speed. Has a Mitsubishi of Japan M51081P 7200 integrated circuit which we believe to be a self timing chip and film speed sensor. We don't know what camera it was made for and don't have voltage requirements or other specs. There are 12 wire leads coming from four different areas. Assembly is 68mm long by 50mm wide. Shutter opening is 17/32". Unused in original static shielding bag.
