Goens says, c. 1858-1947, Sheffield England. Made all types of cutlery and hardware items, including "Bowie type knives. He also shows 2 different "bells" stamped, one from 1858 and yours from 1859. value, who knows, but probably in the $100-$200 range? Not sure if it had a guard or not but I donot see any evidence of one. Sheath looks to me not to be original. Interesting ole knife though!
