Also upon searching for more examples I've found that apparently the Romanians had some similar fun with jigs and drill presses and this only further confuses me. God I love weird examples of surplus but fuck do I hate knowing it'll be very hard if not impossible to find information on why these exist (and knowing the real reason is probably a very boring one). Also if the burrs are on the outside of the mag, does that not mean they were drilled from the back ("interior")? Especially that lower hole where you have no way through both sides. Would that not mean these may have been drilled prior to spot welding the halves or do burrs form on the top or both sides of a hole drilled in thick sheet metal? I can't say I work with anything but thicker copper sheet, and that's very rarely and it doesn't like to form burrs when drilling.
