Arrived today. What a lovely thing. It's titchy too. The period description from Leica says it is three inches long and weighs ten ounces, which seems about right. I've dated it at 1937. After a quick check it looks good. The optics seem clearish, the focussing and iris move as they should, and the rangefinder couples ok.
Ive given the front and back optics a quick clean, cleaned the metalwork a bit, and taken a couple of test shots. I'll post them when the film is finished. I will comment that it slows the use of the 111c down - something I'd thought impossible!
Nice lens if it works ok. Cheap enough to take a punt on if it didn't, and I can always send it off for a CLA. Win-win 😀 .
On reflection, after having the lens in my possession for a few hours, I think I'll send it off for a professional CLA sometime soon.
