Kodak Retina IIIc 35mm Film Camera with Schneider Retina Xenon 2.0/50mm UNTESTED/ When the shutter releases, sometimes the diaphragm inside the lens gets stuck. Sometimes when I forward the film advance, the shutter fires, but the diaphragm does not open. This camera is very clean. International Buyers must contact me before you Buy. Shipping charges will be higher.
