The made in Holland mag is, in outwards appearance, identical to the Mauser Parabellum mags offered with the Original Mauser offerings in the early 1970's The spring was very different in that is was a little less strength then the Mauser mags, but still bear strong, and ultimately, they blow the plastic bottom, right out of the bottom of the mag!!! (MEC-Gar learned the very same lesson, only it took a bit longer, as the follower spring was not as strong!)
That is probably why that "Franzite" looking replacement is on/in there?
Don, is right in that it would cost about $40.00 to put a nice walnut or aluminum bottom in it, maybe even a Swiss bottom if you like the color? Along with a new correct coil, (not box") type follower spring, and the original brass follower guide, spring cap... and re-pin... Aaaaahhhh, my work here will never be finished!
best to all, til....lat'r......GT....
