Maniac/Charlie -
I've got an M1 carbine that I purchased from DCM back in either late 1960 or early 1961. It's a Saginaw S'G', 18635xx, with an Underwood 9-43 barrel. It was rebuilt at Rock Island Armory sometime between 1947 and 1958 from the RIA over EB boxed cartouche on the left side of the InlandType 3 stock.
I'm new to carbine collecting; what's UEF? Underwood barrel presumably, but what's the EF stand for?
