I wish I could have had Johnny with me last weekend when I saw a lettered 1940 M1911A1 U.S. Army. The frame had the GSR marking and the serial number matched the letter and I believe the stocks were original but then again when it comes to the military models and all the markings to deem it correct I'm lost in the ozone. A letter tells where it shipped but one can't determine authenticity of all the parts unless they know their stuff on those, which I don't. It had a price tag of $6500 and was in incredible condition but there again, what exactly does one look for. It had a polished slide and frame with the parkerized topstrap and bottom and back of the frame so that kinda threw me. Sorry to get off topic on that but Johnny and Scott are the go to guys on these military 1911's.....Vettepartz,surely you know by now that when JohnnyP speaks you will always learn something! I'm nearing 70 years old and can't remember what I read last week I don't know how JohnnyP does it but, between him and Scott Gahimer they pretty well cover all the bases. Nick
The markings are correct the S/N was No719796 but the frame finish resembles my Series 70 GM, the stock panels look correct on the one I saw. I did snap 2 quick cell pics so I'd remember the pistol. I recalled correctly that the bottom part of the frame had the finish you described as being blasted then blued. SO...throws a flag up for me. Sorry for the drift on this thread. The gentleman did say the barrel was G marked but obviously, since I was only looking, I couldn't have him break her down to check. This is what this forum is all about. Someone who may have been taken in by the letter and condition may have bit on a pistol seemingly incorrect. Thanks Johnny...and again sorry for the thread drift but I did mention the G barrelThe acceptance mark is CSR for Major Charles S. Reed. If plastic the stocks would have been Coltrock which look like the early hollowback Coltwood, but have no mold numbers on the back. The Coltrock proved to be too brittle, and Colt went back to the full checkered wood again until the 727000 serial number range where the Coltwood was then used.
The most important thing to check is whether the slide is serial numbered to the receiver. The slide serial number is found under the firing pin retaining plate.
From your description the finish was not correct. The areas you describe as Parkerized were actually sandblasted and then blued. This was not done on the military pistols.
This is a 1940 CSR accepted Colt 1911A1.
