M-1 Carbine mags

[GuyW]

I want to be able to ID USGI M-1 Carbine mags, and commercial mags.

I have several 15-rd and 30-rd mags bought at gunshows in the early-to-mid '80s (these guys had crates of 'em)...and I kinda thought they might be commercial Korean stuff.

How to tell?

Thanx

Yes - especially the portion about genuine 15-rd USGI mags not being faked at this time because so many were made in WWII, and are being sold new-in-wrap from crates at gun shows, even now. I think my 15-rds are genuine USGI, not commercial...

...I won't be selling my good-running 30s in any case...
