I have my great grandfathers Win. .32-40 Lever action that he got in trade for drilling a well in 1891. The gun is in perfect shape because he only hunted with it once and it has set in a cabinet since. The original box of shells he got with the gun are still there (half of them). This rigle has the long hex barrel. Is there anybody out there that would have any idea to the guns worth, dollar wise?
