Interarms/Mauser magazine ID

[Augsburger]

I've seen all three types of mags come with NIB Interarms...Mauser marked, Dutch marked and Dutch manufacture unmarked. All have bare steel retaining pins for the base of the mags. (see Pete's pics) The crimp mark at the top of the mag also never extends to the edge of the guide rib on the Dutch manufacture mags, Meg-Gar mags do. Also visible in both sets of pics.
