I've been filling out my magazine stash as of late, and am now heading down the road of a "collection". In pursuit of this, I've been looking at procuring some of the lesser known magazines. I scored a sweet 40-round Bird of Prey magazine this past weekend that is in great shape. I also picked up two supposed South African Defense Force magazines, but have some questions. One is the old style with folded and spot welded, and one is the new style with the flush seam in front. The one with the flush seam has a questionable "Defense Force" mark. It kind of looks like someone may have taken a very fine carbide cutter and put the Defense Force mark on it. Other differences are in the insertion stops - the ones on the newer model mag aren't as dimpled as the older ones. The font is also different on the one I believe to be a legit Defense Force mag as it's not the regular font found on all the other common mags. Can anyone with any experience with these magazines confirm this is a legit South African Defense mag? Did these mags come in both early (folded/spot welded seam) and late (flush seam) types?
