M1 carbine mag question, when did production end?

[Robb]

I picked up 4 "new-in-wrap" 15 round M1 carbine mags. I'm curious how old they are, when did production of USGI 15 round mags come to an end? I did a search and couldn't find what I was looking for.

If anyone is curious, 1 mag was in great shape, 2 were nice for as old as I imagine they are and 1 was very rusty. Buying them in the wrap is definitely a roll of the dice.

They used the M1carbine well into the 70's in the military,and at least into the 80's for law enforcement and prisons.So it probably would be safe to say the military produced them up into the 70's.

Check to see what markings there are on them and you can look up the markings and maybe determine age that way.

Take some oil and steel wool to the ones that are rusty,they clean up rather nicely as long as there not pitted ;)
