The mods you mention would not have been done during an arsenal rebuild. They only repaired / refinished as necessary to return the pistol to original mil spec standards. Most G.I. 1911s have been rebuilt at least once
IF it was 100% Remington Rand, you might have an even swap. 100% Colt would be close (with a few $$$ tossed in), but not as valuable as a 100% RR. Since it isn't, keep your Colt.
I have a '*******ized' WWII era 1911: Remington Rand frame with Colt slide. My research found that this was common place, as pistols were often disassembled and cleaned by unit armorers, in bulk, then reassembled from the pile of parts.
Ahhhh, the hidden curse of mass production....
The "AA" stands for Alabama Arsenal. (A pretty small operation) They were one of several arsenals that did rebuilds just before and into WWII. Often in WW I,the ordnance teams were with graves registration on the battle fields to reclaim weapons, and clean them up for re-issue. Very often weapons were missed or forgotten. Some 1911's were still in balls of rust and mud when they arrived a AA years later. The typical clean-up treatment for these was to dump them (dis assembled if possible) in a large drum tumbler with corn cob media for a few days or weeks and clean them up enough to work on. If a slide was pitted badly it was scrapped, but frames were rebuilt if at all possible. I've seen WW I frames that were so smooth they were blank when re-parkerized and had to have a SN stamped on (Starts with a five pointed star) These got fitted with whatever parts came to hand. Some of these gun look so bad they were never issued and many others went Lend/Lease, most likely to never be seen again. I doesn't sound like your friends 1911 is worth your commander in anything close to an even trade. But a good 1911 or 1911A1 but not NIB is still probably worth a lot more than a brushed nickel Commander. I did see a GI issued but not used Colt 1911A1 with papers and photos (Issued to an OCS grad in August 1945) sell in a face to face for $3000 in about summer of 2000. And you know those guns, the prices have gone way up! Ivan
Great stuff, Mickey D. What's the scoop on Ogden (Utah) Arsenal weapons inspected by Elmer Keith and somenen else whose initials are EK?
LOL kind of funny you say that since his gun is a colt frame and remington slide the exact opposite of yours. Anyways I am definitely keep my colt commander. But to throw a twist in things I am probably gonna buy his WWII 1911 since he offered it to me for $675.
