I looked for info on this bayonet which I believe to be for a M1. Any help is appreciated on this particular one. The markings I cannot find anywhere I've looked. Serial number is 42396 and the letter "C" above it. The blade is 17" long.
Mods, feel free to move if posted is the wrong place.
Thanks,
Slim
