Hello, My grandfather found this bayonet in his garage in the 1940s in the US. So far we have not been able to identify it.
Here's what I know. The entire bayonet measures 22". The socket portion is 2 5/8" with a serial number 105227 on it. There is also an identifying stamp on the portion that attaches the blade to the socket. It is an oval standing up with a plus sign(+) over a "v" within it. There are no other identifying markings. If you looked into the hole of the socket where you would insert the barrel of the gun there is a large circular hole with a notch at the bottom resembling an upside-down house or a box with a "v" under it. If you cut a cross section of the blade it would be in the form of a "+".
Please share any information you have about its history. Thank you!
