The guys are right on on their prices, however did I read right that the stock is not original? If you do not have the original stock in good shape, those prices come down alot. Probably around 500-600 or so if that in most cases.
If you have the original stock for it I would consider wrapping it with either a gunsock or keep it in a gun case with some humidity removers thrown in to stop warping, Being that it is not on the gun. I have seen old factory stocks stored in a safe, that the forend would warp toward the barrel groove and can make it difficult to reinstall the barrel, this was a rare case, but would hate to see it happen again.
Hope this helps
Ballistically Speaking, Im about a 300 FP with a BC of -1.
