sure nuf Colt's Pat. Firearms Mfg Co., Hartford, Conn.
Believe it or not, US gun companies made a lot of different things.
...it was more likely made by Remington Rand, a typewriter and business-machine manufacturer that received one of many WWII contracts to produce military firearms. Union Switch & Signal was one that lost its contract to manufature 1911A1 pistols because too many were being lost as "lunchbox specials," so they ended up producing receivers for the M1 Carbine, as subcontractors for a couple of the "prime contractors."On the other hand I used to have a Remington 1911, so to these manufacturers I guess metal is metal.
Didn't Singer (as in the sewing machines) make some 1911's during WWII?
