Ben's list (admittedly wrong as there >were no M series list before 1953) lists this number as 1943 Elmar 3.5/50 is coated since 1946. First coated Elmar = # 581.501. Changement to international focus stops (3.5, 4, 5.6, ..., 16) in 1946 also. New optical construction since 1951, and # 905.000. Elmar since 1954 with M bayonet. Maybe you might identify the year by the focus knob, there are 4 different types (flat top, bell push, without infinity lock, and "normal" type). Maybe somebody else knows the intro years of the different focus knobs? - -Alf
