I thought I would kick this topic off with a post of the markings on a couple of my magazines.
These both came out of a mag pouch I got from an online auction site
And not the NZ one either
The markings relate to manufacturers, and on another M1 forum I visit overseas they have some good info on who the manufacturers are.
I would be keen to see, or hear about, any other collectors magazine markings, and for them to post if they know what they are, and even better maybe help identify some that are not known.
