Nice. And very collectable.
Mine is made by IBM. Also got it from Anniston through the NRA DCM program early to mid 1960's. Paid $20 for it. And speaking of non traditional military contracts you mention, I have a M1 Garand National Match made by International Harvester.
At a gun show in Columbia SC sometime in the 1980s, Beard autographed his book on Carbine Williams for me.
I met Williams at a gun show in Charlotte NC in the early 1970s a couple of years before his death. I regret not having him autograph my M1 carbine. Or the box my Colt Ace came in.
Williams had an interesting life whose career as gun designer began as a part time moonshiner serving time in prison for the murder of a deputy sheriff during a raid on his still.
