This is a solid representative example of a 1920 production U.S. Springfield Model 1903 Mark I rifle with "S.A./flaming bomb/2-20" marked on the barrel, fixed blade front and folding ladder rear sights with volley notch, "U.S./SPRINGFIELD/ARMORY/MODEL 1903/MARK I" over the serial number on the receiver, correct Mark I style straight grip stock with a recess below the ejection port for the Pedersen Device, full length handguard, ling, and correct Mark I cut-off and correct Mark I disconnector in the sear. The stock is marked with faint arsenal rebuild inspection marks on the left side and a single circled "P" on the inside of the wrist and has a smooth steel, trapdoor buttplate.
