which is nice

So we're not talking about an absolutely perfect Vitessa

What does 1891 mean

a short telephoto (looks like it's meant to fit a 135mm) and a bit of extra film

Leitz 5cm f2 Summitar for LTM air which is niceThis is a first year (1938) Leitz 5cm f2 Summitar lens for Leica Thread Mount in good usable condition, with clean glass and smooth focusing but a fair bit of cosmetic wear, mostly on the collapsible barrel. The focus tab infinity lock (the spring loaded part) is missing, which is technically a flaw but honestly, it's a usability improvement. Good imaging. A nice vintage lens with the "old" aperture sequence (to f12. 5)
