Selling these for the price of shipping & handling
The Pentax MX has an accurate light meter and it winds but after you cock it you have to put a little pressure on the lever so it fires. Nikon ME battery compartment is sealed with acid, shutter cocks and fires. Minolta is dead and the FG 20 seems to work but missing shutter button mechanism. For these reasons they're offered for parts. The battery caps and focusing screens alone cost more than my asking price.
