Chandos After the German Army seized Norway, they found that their Leica cameras would not function effectively in the Northern part of that Kingdom during the winter of 1940/42. As a result, Leitz developed the IIIc(K), the last initial for "k?gellager" or ball-bearing. This version had the pin-bearings on the shutter replaced by ball-bearings. Later, Leitz found out that only one ball-bearing was necessary and this has remained the rule to this day. Zeiss Ikon was also asked to produce special cold-weather Contax cameras and did so by producing a run of Contax II and, perhpas, III cameras with almost no oil. These cameras are marked "K" -- though, in this case, for "Kaltfest" or "cold-conditioned" -- internally and are not well known though Bob Pins seems to be the expert on them. I have never tried to use a Leica I or II in cold weather. My Postwar IIIc, IIIf RD, and IIIg, as well as my M3 and M6, seem to be unaffected by ambient temperature.
