Military History/Bayonet Knife Identification
Sir, I received this M Series bayonet in this poor condition. There were no grips and no guard on the bayonet knife. The butt plate appears to have never been removed. My question is whether this is a M3 or a M4 bayonet. You will note an oddity of only 1 hole in the Tang leading me to wonder what type grip(s) would have been on this bayonet. The bayonet was in a US M8A1 PWH scabbard but that may not be the original scabbard. So my question is:
(1) Is this a M4 bayonet or a late M3 knife blade refurbished with a M4 butt plate,
(2) who was the manufacturer,
(3) with only one hole in the tang what grips were utilized, and lastly,
(4) are the Retainer Pins the removable type.
I want to reinstall the correct guard and grips to original conditions if I can.
