I bought mine many years ago at a show in Pikesville, MD. It was in a white Buck commercial M9 box and in a standard Buck commercial scabbard. Joe Houser at Buck Knives told me that they had some contract over run blades that they sold as commercial bayonets. A few years after that I was able to pair it up with a brand new Australian marked scabbard that a former Buck employee had and was willing to sell.
The bayonet pictured looks right to me. Too bad someone had to try out the wire cutter.
