Well, I can't be sure of the date as with this gentleman, who has had it since the 60s, but it sure does look the same....green handles, same markings, etc. I purchased it from an old guy that had a knick-nacky gun store with a bunch of old Nazi rifles/pistols, etc. He was in poor health, and closing his store. To be honest, I never gave it much thought...I'm not a connoisseur of fine bayonets; bought it, and threw it my closet, with the mountain of shootin gear I have.
I'm currently away from home, but when I get back in three months, I'm gonna dig that thing up and give it a look....if it is the same I will be a super nice guy and let some lucky ARFCOMMER have it for a steal at $1300.00
BTW: If you're interested in it for that price, I also have a Bushmaster M4 that was issued to Double-Secret Navy Seal/Force Recon/Delta Force Operator Super Commandos in 1993 because of repeated failures with their Colt m4s. I could probably let it go for $3000.00.
Edit: I have many other Double-Secret tactical products in my inventory that could be let go for a reasonable price (don't tell anybody else, though, I might lose my Double-Secret security clearance if the Govt. finds out)
