I think the article about the Parker upgrader down south, said it all.
He had upgraded many shotguns, never misrepresenting them, just selling them.
So that potential buyers could think they were getting a good deal based on the premise that they were the sophisticated buyer, and he the unsophisticated seller.
Peoples avarice allowed the ruse to continue for decades.
I dont usually pull stocks off refurbished guns, and Ive never encountered a seller that allowed it, so I think Bob is covered on the hidden roughness.
