how much are they worth

i have a nitro hunter 12ga 36'' barrel made in early 1900's and a 222 savage 340B model can you tell me how much there worth?

hello steven,,i know i've seen the nitro hunter shotgun but can't remember who made it ,,any name on it other than nitro hunter?,,just too many shotguns in the book and i know it isn't listed as such,,as for the savage 340 b it's worth around 225 good-350 if really clean,,good little starter rifles or varmit hunters ,,and very dependable ,,
