Manufactured in 1960. This camera is automatic exposure only with no manual over ride possible. Its a solid metal camera not like the Optima 1a which is plastic. Three zone focusing with pretty setting symbols! and a frame counter on the back below center of film door which counts down.

Fun with this camera.
Just cleaned it so far, seems OK. Not tested yet though.
