Looks like you have a mismatched trench gun. Both the receiver and the barrel were shipped as trench guns. 57808 was shipped in late June 1942, and 61274 was shipped in early July 1942.

If you can provide the serial numbers of the receiver and barrel I may be able to tell you exactly when they shipped from the factory and in what configuration.
