Reflex-Korelle III with Carl Zeiss Jena Tessar f/2.8 8cm. I believe was manufactured in 1939, possibly the last model produced by Franz Kochmann before the war. It is in Mint Condition except for the shutter the lags (does not close all the way as you can see in the far right pic). Has anyone had any experience with this particular model iii? Thank you.
