Marlin Lever Action Rifle Serial Numbers 1883 to 1906
(Including Models 1881, 1888, 1889, 1891, 1892, 1893, 1894, 1895 and 1897.) Note that records are chaotic as all models were numbered in a single serial number range, and numbers are often duplicated, and the dates recorded are apparently shipping dates, not dates of manufacture. Brophy studied the records and came up with the following as dates of manufacture.

MARLINS MADE 1948 and LATER
Marlin Model 336 and Models 39-A and 39-M manufactured from 1948 to 1968:
A one or two letter code was used to designate the year of manufacture.

All Marlins (except lever action) manufactured from 1962-1968
A two letter code was used to designate month and year of manufacture.

All Marlins manufactured from 1969 to 1990:
The first two digits of the serial number designate the year of manufacture, either as the last two digits of the year (in 1969-71) or as a number code (1971 and later)..
