Hi everybody, I am new to the M1 carbine group. I bought an Underwood about a year ago and it shoots great. My question is, who manufactured the bayonets for this carbine in WWII? I saw one at a gun show that was suposed to be an authentic bayonet. On the bayonet by the handle it was marked. KIFFE JAPAN Would this be right? Another table at the show that had lots of bayonets had a book that showed a picture of this same bayonet (leather handle) as a WWII era bayonet. I did not catch the manufacturer name though. It just seemed strange that it would be from Japan. I saw some Vietnam era M1 Carbine bayonets that had plastic handles but this was the only one I saw with the leather ribbed handle.
