I have 2 of these and thought that another collector may need one for his/her collection.

This is a Colt 1911 known as the “Black Army” due to shortcuts used to rush production for WW1.

here is what the stamping identifies

Slide - made between 1911 to 1913 due to last patent number on slide being February 14, 1911. The Rampant Colt (little worn) is on the rear of slide. It was moved to center of slide around 1918. It also has the original “U” notch rear sight.

Frame - SN dates it to 1918, behind trigger is Springfield Arsenal acceptance stamp. Above trigger is “AA” which indicates this pistol went through Augusta Arsenal for rework/inspection after WW1, most likely for WW2 service.

Magazine does not appear to be the original WW1 version but a later version for WW2.
