About all I can say is that they are earlier pinfire rounds, probably for revolver use. Pinfire guns were much more popular in Europe than in the USA, ca. mid -19th Century. There were also pinfire shotshells made. No idea what the 2 headstamp means. There are cartridge collectors who specialize in pinfire ammunition. This guy is the acknowledged pinfire expert. I strongly suggest you contact him pronto. You could could have some serious value there if you have 1000. Pinfire Ammo for Sale
