'Duke1168' - Welcome to the KCA Forum.

Pictures are invaluable in assessing exactly what you have. Close-up, clear pictures of various areas and details are much more useful than 'over-all shots'.

BTW - There are two versions of stocks that are commonly seen on model 1898 carbines:

The first and most desirable version is similar to the model 1896 carbine stock. It is usually inletted on the left-side of the stock wrist for a sling-bar & ring and it is approximately 30 inches long.

Model 1899 carbine stocks were later used on model 1898 carbines during rebuild and repair. These stocks have a longer forearm, with an overall stock length of approximately 31&3/4 inches.

All U.S. model 1896, 1898, and model 1899 carbines have their barrel-band retained by a 'flat band-spring' inletted into the right-side of the forearm tip.

(If your stock is lacking evidence of this band-spring, it is a 'cut-down' rifle stock. The 'tip' is likely patched with a wooden plug, since shortening a rifle stock exposes the routed-out channel that 'lightens' the stock).
