50 or so
i got a 12 gauge king nitro double barrel double triggers and double hammers no serial number on it
There were many thousands of the Shapleigh King Nitro 16 Gauge with a double barrel. For the most part, they are worth about $50 to $100 depending on mechanical and finish condition.
I have one, double nitro breech, and a hexogan barrel half way down. Never seen one like this.
John - The Nitro Special name was used by J. Stevens Arms & Tool Co. You didn't tell us what kind of a shotgun it is, but I suspect it is a break-open breech single shot or double barrel. It may have side-hammers, or a boxlock with rear hammers or a hammerless boxlock and the barrel(s) may be either laminated or fluid steel. All those things and the condition of the gun will affect the value. It MIGHT be worth $250 if it is a good to very good boxlock with fluid steel barrels or less than $10 for any variation in broken/worn out/rusted condition.
You will have to state who made it.
