From the 1980’s. The bayonet and scabbard measures approx. 13.5 inches long and the blade measures approx 6 5/8 inches long. Scabbard stamped ” M8A1 ” as shown. I’ve seen several of these with and without the MADE IN W. Although not stamped, I’m pretty sure this was German Commercial made bayonet by A. What you see is what you get. I will be listing a few more bayonets from my collection so please check my auctions regularly.
