In the Novella that Jim Harrison wrote- and later sold the rights to Hollywood for the movie-The double that Tristan Ludlow brought back for his Father was a 12 bore Purdey hammerless. Of course, Jim's story was 'altered" and true story- he was just a chain smoking starving Michigan recluse writer who loved to drink and hunt grouse with his prized Setters. Jack Nicholson took a liking to him, and staked to a loan for $15K to help him over the hump-- after the movie came out, Jack received a registered letter with a hand written thank you note and a cashier's check for $17,500 enclosed- repayment plus interest. Nicholson was astonished- He told his close pal Harvey Keitel-"Hey, I had it as spare change. No one ever before that I helped out with a loan ever said "Thanks" yet alone paid it back.. I find that quite telling about Jim Harrison's character and upbringing-- he also wrote another novella entitled "Revenge" and Hollywood made a movie of that with Kevin Kostner and I believe the last movie role the late Anthony Quinn played before his passing--I hold Jim Harrison to be one of the best writers to ever come out of the MidWest--
