Here’s what I believe is an 1897 Krag bayonet with scabbard, probably from the Spanish-American War. It’s marked “1897” on the blade, and “lNY143” on the belt clip on the scabbard. It’s covered in some gunk that I can’t identify.
If you happen to know anything at all about this blade, please comment! I’ve had it since I was a kid and I’d love to learn more about it.
