When you’re talking about guns that are this old, that have been stored this long after surviving who knows what length or intensity of Army service, very few of these 1911s are likely to be in mint condition, and most will probably have issues that need to be resolved.
That said, if any rare 1911s, like those made by Singer or US&S during the wars, will be pulled from the lots and sold on individual auction by the CMP, the story says, which is usual.
The guns in the crates may have been manufactured by Colt, Ithaca, North American, Remington Rand, Singer, UMC, and Union Switch & Signal as well as Springfield Armory. They just won’t know until they open them up.
The CMP ranks and grades the surplus M1 Garand rifles it sells, so it’s to be expected they will do something similar with the 1911s. This will dictate their price based on the market.
