Pictures showed up last night.
Interesting carbine you've got there. And it is a Carbine. Officially its an M1884 Carbine. According to my reference material it was produced in the 2nd quarter of 1888, at the very tail end of that run. The next year, 1889, 5000 carbines would be produced in the first 2 quarters of the year, and those would be the last regular Carbines produced until the introduction of the production Krag Carbine in 1985. I suspect the Cartouche is well rubbed and its hard to say what that number really is. But I'd hazard that stock is original to that Carbine.
Your's is further identified by Collectors as a Model 1890, as it has been retrofitted with the M1890 barrel band with integral sight protector. This was done as the carbines circulated back thru the armory's over the years, maybe half of the production recieved these before the carbines were surplused out. Its a very nice looking carbine, Well used but fairly well preserved. I'd say $2000 give or take $250 depending on how the bore cleans up. You might be surprised what a good scrubbing will do.
