Up to 1942 Bausch & Lomb, Rochester USA used a numerical scheme when all of a sudden 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: 1 1876 32000 1900 170000 1924 150 1877 33000 1901 175000 1924 350 1878 35000 1902 180000 1925 800 1879 40000 1903 185000 1926 1100 1880 45000 1904 190000 1926 1450 1881 52000 1905 195000 1927 1750 1882 57000 1906 200000 1928 2000 1883 63000 1907 205000 1929 2500 1884 69000 1907 215000 1929 3000 1885 76000 1909 225000 1930 3800 1886 82000 1910 230000 1931 4500 1887 86000 1911 235000 1932 5300 1888 89000 1912 240000 1934 6375 1889 95000 1913 244000 1935 7600 1890 98000 1914 247000 1935 9200 1891 104000 1915 250000 1936 10000 1892 110000 1916 260000 1937 11700 1893 120000 1917 270000 1938 13900 1894 129000 1918 280000 1939 17000 1895 135000 1919 290000 1940 20000 1896 140000 1920 300000 1940 25000 1897 148000 1921 310000 1941 28000 1898 155000 1922 320000 1942 30000 1899 160000 1923 _________________ Klaus - Moderator 'S'il vient à point, me souviendra' [Thomas Bohier (1460-1523)] http://www.macrolenses.de for macro and special lens info http://www.pbase.com/kds315/uv_photos for UV Images and lens/filter info http://photographyoftheinvisibleworld.blogspot.com/ my UV diary http://www.travelmeetsfood.com/blog Food + Travel BLOG Currently most FAV lens(es): Hypergon f11/26mm Zeiss UV-Planar f4/60mm Lomo Уфар-12 f2.5/41mm Nikon UV Nikkor f4.5/105mm Zeiss UV-Sonnar f4.3/105mm CERCO UV-VIS-NIR f4.1/94mm Pentax Quartz Takumar f3.5/85mm Rodenstock UV-Rodagon f5.6/60mm Pentax Ultra-Achromatic Takumar f4.5/85mm Voigtländer Apo-Macro-Lanthar f2.5 125mm SL
