In World War II, to facilitate rapid production, the Model 1903 underwent some modifications, and as the Model 1903 A3, made on contract, was equipped with an adjustable rear sight set on the bridge of the receiver.  Some of these limited standard, contract arms, had parts, such as trigger guard, bands and other furniture stamped rather hastily out of sheet metal. 

     Our specimen is marked on top of the receiver “U.S.” REMINGTON” “MODEL 03-A3” and serial number 4194698 in four lines.  The barrel is marked behind the front sight “RA”, flaming bomb, “12-43” indicating the date of manufacture.  The bottom of the stock behind the trigger guard is marked “4” “P” in two lines.  The bottom of the stock in front of the trigger guard is marked with four cartouches, “13” “M” “72” “OG”.  The left side of the stock under the receiver is marked “RA” “FJA” and a design.  The left rear of the stock is marked “OG”.
