I think they're probably OK. All other original Erma mags I've encountered seem to be built quite well. These would be post-war, until when I don't know. They eBay out at around a hundred bucks, give or take. The other stuff like Triple K is cheesy, lighter gauge steel. Many are not marked as to maker. Sticking with what's the best available in our hemisphere will help ward off feeding problems. I'd buy one, if I could score it cheap enough, just to try it out.
