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.
