|Zeiss Ikon Super Ikonta 531, 6x4.5 with Tessar f=3.5|
Zeiss Ikon Super Ikonta A, catalog number 531. Prewar, with uncoated 75/3.5 Carl Zeiss Jena Tessar. Coupoled rangefinder, Albada finder. Note the Zeiss-Ikon nameplate, some have this, some have the more usual impression in the leather. Note also the polished aluminum edges; this was done after the camera left the factory, probably because the black enamel became chipped (very common problem). In this case, and a few others I have seen, the removal of enamel and polishing were done so nicely that it looks almost like it was meant to be that way.
