Dave, the Parker was listed in Charlie Price's Serialization Book as being originally made with a pistol grip stock. I think that's where Amoskeag got the idea that the stock had been replaced. The "grip style" in the Serialization Book" is not at all reliable in the .410 category. Of course, I didn't see the gun, so can only guess. However, since it sold for over $20,000, I am sticking with my guess.
