Manufactured in March of 1943, this U.S. Remington 03-A3 rifle is bearing the one and only milestone serial number 3500000. It was likely made for presentation to an important individual in the Remington Arms Company. Commencing with serial number 3000000, Remington Arms Company started production of M1903 rifles under the lend-lease program in October 1941. After the attack on Pearl Harbor, production was redirected back to the U.S for its own wartime use. These Remington Model 03-A3 rifles run in a continuous serial number sequence shared with the Remington Model 1903 rifles manufactured prior, making this the 500,000th production 1903 rifle off the Remington production line! Blade front and adjustable peep rear sights, "RA/3-43" marked barrel, blued "R" marked bolt, and "U.S./REMINGTON/MODEL 03-A3/3500000" marked on top of the receiver ring. The stock is unmarked, with notably handpicked highly figured fancy grain walnut with beautiful colors, and a steel buttplate with flat square checkering.
