Needs to be able to accommodate 50mm f1.5 lens. The case for the III is slightly taller to allow the case to close over the meter.
Have a case for a Contax II (without meter) to sell or swap. I believe the nose of the case will probably hold an f3.5 Tessar, but not the faster (larger) lenses.
Have other cases to sell or swap: Zeiss Messe Ikonta 2-1/4 x 3-1/4, one for a Zeiss 6x6 Nettar (?), another for the Contaflex Alpha.
