The modifications to the IIIc were mandated NOT by the conditions on the
Eastern Front but from the conditions in northern Norway but the results
were the same, the addition of ball-bearing races to the shutter curtain
rollers in place of the earlier pin-bearings.  These cameras were called
"K" cameras -- for 'kugellager', or ball-bearings -- and most are so marked
behind the serial number.

Zeiss Ikon also cold-proofed Contax cameras but did so by removing
lubricants and loosening tolerances.  Many cameras so treated were marked
internally with a painted "k" but, in this case, it stood for "kaltfest",
or 'cold-proofed'.
