This is a very fine original example of an early underwood contract production M1 semi-automatic carbine. "U" marked blade front and two leaf, flip up rear peep sights, Underwood barrel dated "4-43", type I narrow barrel band, unmarked push button safety, unmarked smooth magazine catch, solid milled trigger guard with "flaming bomb" stamp, blued flat profile bolt, and "U" marked hammer. Low wood pistol grip stock with two rivet handguard, large boxed "U.E.F./G.H.D." cartouche on the right side of the stock without the crossed cannons ordnance marking, "I" cut oiler slot, "PU" marking in the sling recess, and checkered stamped buttplate. With oiler and canvas web sling.

Exceptionally fine with 85% plus original gray parkerized finish remaining, areas of some brown patina, edge wear and cycling marks, clear markings, and areas of darker spotting. The bolt retains 80% original blue. The stock is also very fine with small dings throughout, light but legible inspection marks, and brown patina on the buttplate. Mechanically excellent.
