I'm just going to make this easy on everyone...this site has a serial number entry, so its automagical
http://oldguns.net/sn_php/marlinlookup.php

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

The code is on the barrel, usually just underneath the stock's forearm.
it is NOT the JM in a circle...that's the proofmark.

I have used this before and it is a very nice source of information.

i tried it on my M60, says it was made between 1957-1958, but that can't be right, because the M60 came out in 1960. didn't it? my serial number 2R003xxx, has the 21" barrel , 18 round tube and non last shot hold open bolt. so i do know it was made prior to 1984. any input?

mine also has Glenfield M60 Marlin Firearms Co. on the barrel.

I just purchased a Marlin AD-L , 30-30 lever action. Serial number is 13,880. Can you tell me the year of manufacture. It looks pretty old. Thanks.
