Re: [Leica] Lens numbering / Robert

[Leikon35 <Leikon35@aol.com>]

  Robert - You are on the right track as most of the approx. 60,000 lens that
  were fixed on the non-interchangeable 1A's were of course with 11 o'clock
  infinity stops and had no numbers as they were only considered as a part
  of the whole camera.  After 1932, if these lenses were updated to the stand-
  ardized version (with a little "o" on the back) by fitting the lens to the
newer
  versions (mainly the IId) they would have no s/n of their own.  Elmars with 
  serial numbers below 100,000 are considerably rarer since there are only a 
  few hundred recorded, but that is another story.

<< Charlie,
      Thank you very much for your reply to my recent posting.  Indeed, the
 Leica III (1933) IS a jewel.  Still works fine...  Come see me in 65 years
 with your electronic wonders I tell my friends.  As for the 50mm lens, there
 is no serial number anywhere on the lens.  I checked carefully the front
 rings and cannot see a serial number.  So I guess my question remains, did
 Leitz numbered some lenses on the inside ?  If not, how could they keep
 track of the numbering?
 
      Thank you all for your attention.
 
 
 Robert.
 
 P.S.  If it might help, the lens is nickel plated and has the 11 0 clock
 infinity lock.
