Doug There is some controversey about the dating sequence of Leitz lenses from 1940 to 1950. The conventional assignment sets out that 593738 dates from 1943, one of 539 made that year. Laney states that coating commenced at 581501, but this doesn't seem correct. The initial M production dates from 1954, in which year 1000 M3's were made.
