I am not sure whether this would go in the repair notes forum...
I bought a Leica IIIf (serial 646xxx) with an Elmar (probably bought at the same time as the camera). I bought it blind, but from a shop, which I have buying from a few times and which I know are serious about their business.
Generally, the camera is dinged a bit but does otherwise seem sturdy and rangefinder is clear and correctly adjusted in horizontal and vertical. Speeds all seem okay. Vulcanite is nice and clean. Overall a typical user camera. Price was $450.
I just heard something that rattled a bit in the camera. After looking around a bit I found that the winding knob has play in it, and that the exposure counter wobbles a bit. Further investigation leads me onto the knob itself. Slight groaning noises ensue as I understand the cause of it all. The set screw in the knob is gone - it has gone off to Bahamas on vacation or wherever.
Am I right in assuming that the screw does tighten the rest of the assembly? What size is the screw? Is it a "normal" size I might find in say, hardware store or in a watch repair shop?
There's play and wobble but it does wind as it should. In almost any other old and well used camera I'd disregard it, but here... nah.
I suppose the only reasonable way to fix this, unless I can find a new screw, is to send it back for repair. Arrrh... Another week...
now I am getting paranoid...
If I press slightly on the back, a bit below the rangefinder housing, I can hear a "clicking" sound. Is this normal? Is it the pressure plate making contact with something inside?
Apart from this: one damn fine camera!
