then they changed it to some cryptic two letter + digits scheme. As far as I know only the first
letter is significant for the production date, the second is a code class for lenses, microscopes etc.
The decoding is a s follows:
A 1941 G 1963 N 1962 V 1944
B 1945 H 1959 P 1958 W 1948
C 1949 J 1955 R 1954 X 1952
D 1953 K 1951 S 1950 Y 1956
E 1957 L 1947 T 1946 Z 1960
F 1961 M 1943 U 1942
So a lens with UF 743 means a lens made in 1942 and it was the lens#743 made in that year. 'F' stands for photographic lenses.
I am not sure what happended after 1960 though.
So to be complete, here the serial numbers before 1942:
