Thank you, Raid!  The serial number is 
4176854.  This is part of a run of 5,000 such 
lenses made in M42 and completed on 5 MAY 
1954.  Note the red "T" indicating coating -- a 
marking soon thereafter abandoned -- and the 
qualit?tsmark, a sign of production in the DDR.

This lens is a one-off modification.  As I noted 
previously, there are wartime Zeiss modifications 
of Contax RF BM 2.8/5cm Tessars in LTM but these 
would have serial numbers in the 2,8xx,xxx or 
2,9xx,xxx range.  These lenses would have been 
marked in cm while the lens shown in the above link is marked in mm.
