Hello, For reasons that I don't want to go into here (but am perfectly willing to discuss, off-line), I am looking for a working rangefinder camera that takes Leica threadmount lenses, but does not contain a meter with a battery. My ideal would be a Leica IIIg or IIIf, but working examples of these are priced in collectors' currency, and not suitable for my aims. So, can anyone point me to a possibility? I am thinking mostly about the Canon P and Canon 7 (not the later Canon 7S with its CdS meter). I keep reading about Canon Ps with "wrinkled shutter curtains". Is this a fatal flaw? Can it be repaired? Camera would be used just about exclusively with my 50mm Elmar f/2.8 collapsible. Thanks for any and all feedback.
