Thanks guys for your very important feedback (but in the last series, I had a very important booster, the drawings both of Darth Panda and Colosseum and Nighthunter were superb, in fact, trying to keep the pace was very challenging)!
Based in Colo´s and Nighthunter excellent drawings of the M1903 Springfield rifle, I drew the versions with the more modern woodwork, A1 and A4.
The most important feature of this version is the "c" stock, US Army considered any rifle with a pistol grip stock an M1903A1 despite the markings. It was fitted with the 16 inch bladed M1905 bayonet, and was the standard rifle of the US Marines until Guadalcanal.
M1903A4 was the sniper version equipped with the M73 Weaver rifle scope, but without any iron sights. It was the sniper rifle of the US Army in WWII and Korea, and was in use until the early stages of the war in SE Asia. Cheers.
