You need to look behind the rear sight for who made it and the serial number. The RIA on the stock means it went through a rebuild at Rock Island Armory. The Trimble in the sling well is for the company that made the stock during the WW2 period. Your Underwood barrel is a replacement changed during the rebuild. Underwood stopped making carbines in April 1944 but continued making barrels as replacements. hth
