The nearest I can come up with is a shotgun belonging to a Former U.S. Postmaster General. He was a self made man coming from nothing and becoming an exceedingly wealth individual.
The gun itself is not indicative of the wealth of the former owner. It is probably more indicative if the current owner's.
I have numerous other guns I have bought used and have no idea of their provenance. Who knows the stories some of our guns might be able to tell.
