28.8mm for LTM, 34.85mm for Contax RF, Frank.

Zeiss and Zeiss Ikon were not always zealots about marking items,
incidentally:  the Prewar lens hoods, for instance, generally do not bear
any origin markings, just the focal length of the lens for which they were
intended, and Postwar CZJ front lens caps lack any marking at all.  And I
have come across a few Leitz items which lacked a factory marking though I
acknowledge that these are quite rare.
