[300 H&H]

These rifles were originally made under contract for the Britts in .303 caliber. We eintered the war with too few 1903 Springfield rifles. It was more cost effective, and much faster to remake them in 30/06 for US troops. That is the rifle you have, the US version.

They were made in three places. Winchester, Remington Arms, and Eddystone arsenal. Eddy stone was under the managment of Remington during the production of the 1917 rifle. These are the three markings of who made them you will encounter on the front reciever bridge. They were only made in 1918-19. Original barrels have the stamp of the maker, and a barrel date behind the front sight. I don't know of the markings you show, other thatn inspetors marks or proof marks....I think your barrel may have been replaced, as it is without a date.

They are a fine rifle, in some ways better than the 1903. The cock on closing of the bolt has few admirer's these days however....
