I found one that will be available the first part of Dec.

We had a Singer in the arms room at 526th MP Det, FT Greely, AK  in 1986.   Not sure if it was all matching.   Lots of US&S too.

We had two of them in the arms room in Honor Guard Co., The Old Guard, in 1976/79.

They were worth big bucks even then.  Can't comment on the worth of the two we had vs. their condition, but I remember in the gun value books they were stated to be worth about $2400.  We used to talk about "losing" one and whether or not it would be worth 1/2 month's pay for 6 months.

Kind of funny, but the only Colt 1911A1 in the arms room was the company commander's West Point pistol.  We used to check all of them out of the arms room and clean them up prior to IG inspections.  We had US&S, Remington Rand, Ithaca, the two Singers, but just the one Colt (which we never got to handle/clean because it belonged to the CO and I imagine he had one of the armorers clean it for him.

I know a couple guys that will likely bid on it. Beautiful condition. It'll be scrutinized hard by the serious collectors.

As much as I like and still look for USGI .45's, I just can't imagine dropping nice house money on one. I dropped $2200 on one once and had a really hard time doing that. [US&S] Most of mine cost well under a grand. [averages out to around $700 or so]

Key to looking at 1911’s/A1’s is knowledge of serial numbers marking etc. I have had tons of old solidiers say they were issued something rare like a singer 1911A1 - cursory exam finds maybe a singer slide on what is obviously a Remington Rand frame, or similar

Very cool with an impressive provenance.  It sounds like the original individual owner basically pocketed it back in 1943 while on active duty... I assume there won't be any issues with the fedgov trying to claim it as misappropriated property?  I know if this was a 1933 $20 gold double eagle being sold by the grandson of a mint employee they would be making a stink about it as soon as it was publicized.  

when I first started shooting in the late 70s, a range officer, who had been a pattern machinist at Singer had an "X" serialized one... for his birthday in the early 50's his wife had it bumper chromed for him...

They do get nice stuff over there.  Their catalogs are amazing.

It sold for $414,000.

Damn!

Dear LORD!!!!

My thoughts exactly.
