It appears to have been a U.S. Model 1884 Springfield "trapdoor" rifle. At one time, a stamp on the left side of the grip would have had the date of manufacture, but it is probably long gone.
The barrel appears to be the original length, but the stock has been cut down, basically eliminating any collector value the gun might have had.
In the early years of the 20th century the Army wanted to clear out its warehouses and sold those trapdoors for $1.50 or so, cheap even then. The result was that, like milsurps today, they got little respect and many were cut down for hunting rifles or even had the barrels reamed out for shot guns.
In addition, many companies bought surplus parts and assembled guns of the trapdoor type which sold for little more.
With the general increase in gun values, I would guess that rifle might bring $200. Had it been left intact, and in good shape, five times that would not have been impossible.
