År 1959-193
The Type 037 camera was made between October 1959 and February 1963. It has a built-in coupled selenium meter made by Gossen; the meter readout is visible in the bright-line viewfinder, and is used by centering the meter needle. The lens is a Rodenstock Reomar 45mm f/2.8 in a Pronto-LK shutter, with speeds from 1/15 to 1/500 second, plus Bulb. The film is advanced with a lever, unusually mounted underneath the camera. This is made from plastic (and it is common to find Retinette IBs with a broken lever). The known serial number range of the camera is from 50981 to 274266: thus if the series was continuous, a minimum of 224,266 type 037 cameras were made.
