1936 Leica IIIa CLA and Repair

Giving my 1936 Leica IIIa a CLA. It basically works fine, the shutter fires on all speeds but the slow speeds are sluggish. The curtains have previously been changed, maybe even twice in it’s 78 year history and look good. Overall there is brassing on the top and bottom plates but from normal heavy usage telling me it was well loved. From what I can see, the inside looks clean-ish, no major rust or anything like that.

I did some research and found not much at all on this model but similar models share the same rangefinder set up, but the top plate is slightly different on them. The following is the method I used to get at the insides of the top plate.

It unscrews counter clockwise (ccw) with just your fingers After removing the collar, remove the lens, it should be tight but it just slips out and under that is a ring that holds the lens. A spanner wrench is required to remove it. The lens has spanner slots too, this can be aligned with the ring underneath and both unscrewed at the same time if you have the right tool. Also the lens spanner slots makes it possible to realign the vertical RF image by rotating it until the image is correct.
