I posted this over on the BROW forum and haven't received any answers yet. I've got a chance to trade for/buy a Springfield Navy Rolling Block with a very nice bore. I realize it's difficult to say without seeing it, but does anyone here have any idea of what one of those should go for? It's just a good, honest rifle with a really nice bore, with no major problems. The rear sight leaf is broken, and the cleaning rod isn't correct. Thanks!
