Trying to upgrade to something with a removable prism so here is an OM-1 with Zuiko 50mm f1.8 lens. I am also including another body I stripped for use as a knife edge focusser. Never got around to finishing it up, but it should be easy enough to put a ronchi screen in it. Meter works, but I will not vouch for its accuracy. Cover is missing from the motor drive hole and some of the levers/springs have been removed from the motor drive train. All the shutter speeds work fine and manual advance and counter are ok. I don't imagine may people are interested in putting a power winder on one these anyway.
