My sources state that the model of 1927 were actually Model 1921s, where the receivers were ground down to replace "Model of 1921 Submachinegun" with "Model of 1927 Semi Auto Carbine" and the "Auto" was removed from the frame. Both the upper and lower receivers remain the same as the Model of 1921 and can be easely converted back to FA. They are therefore considered to be SMGs by the ATF

This would indicate that these were Colt made guns originally, not Auto Ordnance.

Auto-Ordnance in West Hurley, NY made a semi starting in the 1980s, which are designated 1927A1s. These are purpose built as semis and cannot easely be converted to FA.
