I have come into possession of this bayonet. I have been told mixed things, one being its british made for the American army and others saying its American made for the british!
There is also confusion as to whether this is WW1 or WW2.

Sorry for what might be a simple question but I am new to all this. The bayonet is marked Remmington 1913. There is also what looks like a crown and the number 17.

Thanks everyone.
