P38 mag

This mag came in an ac42 I picked up today. I've never seen one marked with ac. Any opinions on year of manufacture?

These are "armorers" mags, but often times found in late ac45 pistols and commercial pistols. I have one in an ac45 C block - it should be Wa359 marked on this spine. I'd say later than your pistol though, since it's marked P38v.

Thanks Mike. Where do people post pics of pistols on this forum? I picked up a bunch of makarovs I need to get pictured, so I thought we could start a few sub topics in this forum. Anyhow, here's some pics of the ac42 I picked up today. Found it at Cabella's in their "gun library". Either an unmarked old import or a bringback. All matching, with very decent 80%+ finish. Now I need a 43.
