That's going to be a hard to find, and very expensive, item, especially if the rifle was never converted to 1896 specs (most were).

Is the barrel still full 30"? Is the muzzle crowned, or just flat? Does the extractor have a small pin on top, and is receiver notched at the right rear to accept the pin as a bolt hold-open device? Flat muzzle and no pin would mean you'll need a flat butt stock, with groove for cleaning rod below the barrel. You'll also need the rod, and complete upper band assembly. I've seen ONE loose M1892 stock in 40+ years. Rods simply do not exist, if you need a full-length one, you have have to get a repro. The M96 alteration has the usual 3-pc. rods in butt.

Check out my website (click my ID). #2546 is a completely original Model 1892 Rifle. #6692 has been altered to M1896 specs. Note the numerous detail differences.
