Yes Dirtebiker, it was years ago, (I had my own FFL and table 92-95) an old farmer comes up 15 mins from closing time, and asks if I want to look at a pistol he is wanting to sell in a zippered rug case thingy. I almost said no, I was packing up and dint need any guns but he said it was a .45, and this was a BG (before Glock)time in my life so I said sure.
He unzipped and handed me a 1915 dated 1911 Colt US Army and one two tone mag.
beutiful, wanted $300 cash for it. said it belonged to his grandfather, and this guy was easily in his 60's. I noticed 3 angle file cuts on the frame ^ ^ ^ spaced out like that at the frame bottom of the magwell. I asked him why anybody would angle file ^ ^ ^ to the butt of that gun. Grandpop killed three Mexicans with the pistol he said, and he notched it.
Sits at the very bottom of my safe, wiped down once every year, added a WWI printed manual to the case. My boy will take it to the nearest pawn shop the day after I start my dirtnap and get about $300 from a dealer for it.
