How is the bore? Is the rear sight marked with a "C"? (I can't recall if it's on the left side of the base or the right). Looks like the stock might have been sanded a little, that's why the cartouche is so faint. The bluing is largely gone, especially on the receiver. Will they come down on the price? Will your Remington get you within half way of the cost of the rifle?
Seems to me that recently a Model 1899 went for considerably less than 1k on GB. I'll let the knowledgeable guys evaluate the rifle for you but it appears to be all that it purports to be and I prefer the 1901 sight which is the one you have there.
