Sorry, but your Marlin 1895 was not manufactured in the 1960s. The modern Marlin 1895 was introduced in 1972 and that year they had a B0 (bee zero) serial number prefix. Subsequently, the first two numbers of the serial number designates the year of manufacture. Up to 2000 subtract the first two digits from 2000 to get the year of manufacture and after 2000 subtract the first two digits from 2100 to get the year of manufacture.
