Help with Receiver Markings

[RCS]

Both Rock Island and Springfield stocks without any stock bolts are very difficult to locate. If you do locate this type of stock, it will be on a rifle and not "loose". Original no bolt stocks were also inletted for the open bottom rear sight base too.

So it would seem that I have a rifle that has a previous owners initials stamped into the receiver for whatever reason maybe match shooting or just personal rifle. Most parts seem to match for a M1903 built in 1910, well except maybe the stock.

No inspector stamps on the stock just a few numbers at the top of the butt forward of the butt plate. Looks also like someone did some shimming at the forward trigger guard hole. S stamped at the nose. Any thoughts would be welcomed.

Based on the large S on the foretip of the stock the stock was originally mounted on a Rock Island M1903 - 1913 or before.

That's interesting and here I thought it was a Springfield stock. I was under the impression that Rock Island stocks used RI on the nose tip.

[Rick the Librarian]

They did ... when Rock Island started producing M1903s again, starting in 1917. Springfield used an 1/8" S on the foretip; Rock Island a 1/4" S.

Thanks to all who have posted info so far it has helped a lot. I think I ended up with a really nice rifle and goes well with the 03A3 I have. Needless to say it won't be along it has other friends.....
