I acquired this carbine from the NRA through the DCM program in late 1963. The carbine was shipped from the Red River Army Depot on the 6th of December 1963:

I found the Case USMK4 bayonet and scabbard a while after I received the carbine.

The barrel is an Underwood production dated 4 - 43:

The receiver is stamped National (under the rear sight) Postal Meter and serial numbered with a number that matches the invoice. Maybe someone who has DCM documents for a carbine in their collection can tell me if it was standard practice for the Army to use the barrel manufacturer to document the transfer (look at the above document) instead of the manufacturer stamped on the receiver.

I have the carbine logged in as a National Postal Meter since the serial number is stamped below that stamping on the receiver - there is no serial number on the barrel to tie the two together.

The following photo also shows the SG (Saginaw) stamped on the recoil plate.

The internal marked parts (not shown) seem to be a mix.
