Lee Enfield
While a good 1896 Lee Enfield Mark I would go for $750 or more, the fact that condition is everything. Unfortunately, someone has left your poor old girl out in the elements, and treated her very badly. Bore condition is also a major factor, and you have not mentioned this.
The good news is that it seems fairly complete, with the wood, volley sights, and such intact. The clearing rod has been damaged. (Yes, I said CLEARING ROD, not Cleaning Rod.) The metal is pitted.
A reasonable price should be in the $300-$350 range for a rifle in this condition.
