I am working on an article on German red and black plastic exercise cartridges similar to the ones shown below. I have documented headstamps with codes P, aux, ay, lpk and nts, as well as ones with no headstamps at all. I also have documented one with only EX on the headstamp. This will all be in the article.
What I need is images of the boxes these rounds come in, and if possible, the actual headstamp (or lack thereof) of the rounds that come in the box.
Any help appreciated.
