Images from my 1936 Leica IIIa

After completing the service, cleaning, repair, adjustment on the 1936 Leica IIIa, I shot a test roll to see if everything was working as it should. There are a lot of things that can be wrong on an 80 year old camera. A test roll can show if the film is advancing correctly, getting the proper space between images on the negative, shutter speeds are correct, the rangefinder and lens are in good sync so the images come out good and clear. etc…

The first test roll showed that the shutter ¬†was at the right speed but on the faster speeds, it was not adjusted correctly. The second or “closing” curtain was catching up with the first curtain part way across the film area.

The dark area on the right means the closing curtain caught up with the opening curtain, and is called 'capping' Here at 1/500 speed it is about 75 % at 1/1000 it was almost 100%

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.
