[Leica] S/Ns by Batch # [addendum]

[Leikon35@aol.com]

      In retrospect, I should have added that I just picked 1939 at random --
      but it actually was a very interesting year as there were 6 different
Leicas
      in production in 1939:
      Leica I (standard)  --- 1932 - 1950
      Leica II(D) --------------  1932 - 1948
      Leica III (F) ------------- 1933 - 1939
      Leica 250 --------------- 1933 - 1953
      Leica IIIA ---------------- 1935 - 1948
      Leica IIIB ---------------- 1938 - 1946   ------- Marvin Moss (again)
