My nephew's grandfather gave him this flintlock pistol. He has no need for it wanted to know if i wanted to buy it from him.I am not sure what it is or a fair price. There are not markings on the barrel. Only marking is the word Spain stamped on the inside lock under the mainspring. Lock and trigger seem to be in good operating order and barrel shows no rust in it.I am pretty sure it is not antique. it has two hex screws that hold the front of the barrel to the stock.
