Having spent an afternoon with Bo Whoop during October of the year before it was auctioned at Julia's I can appreciate your infatuation with the great gun, and it's original owner. I have a set of all the reprints of seven of Nash's books and agree with Dean on his unique writing style.
I followed the whole affair from the time Bo Whoop was "discovered/outed" by Jim Kelly, until it was bought at auction by the son of one of Nash's hunting partners, then donated to the DU museum. I was very pleased that it ended up where it did, and had secretly hoped that it would, and would not end up in some collector's dark closet never to be seen again until said owner croaked.
