I recall as a 10 something yr old (would have been around 1938+) seeing the head of Jumbo (the buffalo) displayed on the wall at the museum. I believe my grandfather was with me (he died in 1943) at the time and he recognized Jumbo's ear notch.

I remember my grandfather sitting in our Denver home telling the stories that are in the book, to my mother who was writing them down. She had a big accordian-like folder, in which she kept the pages of stories, which she said she would publish one day. I am so glad that my sister Sibyl did publish them. I remember that my Grandfather would grow so tickled when he told about those escapades on the Nebraska plains, and in Wyoming. He could hardly contain his humor when he told about the Stinkin' water river, flowing into the Frenchman (river), as it does near Culbertson, NE. My Grandfather was quite a story-teller and I think he believed that a really good story deserves some embellishment. The story in "My Life on the Frontier" about two bothers accidentally killing an elk is one case in point. Here are two versions:
------------------------
From My Life on the Frontier - Deer Hunt to set Bear Traps Ch 49 Stories by J.A.W Hudson
Noah had his gun tied on the saddle under his stirrup strap, and I carried mine across the saddle in front of me. Mine was a single shot Winchester, a splendid elk and deer gun.
Noah says, "Gimme your gun, I want to kill that elk." I handed him my gun and some cartridges out of my belt and he started to sneak up on the elk. It saw him, and started to run so he started to shoot the elk, but before he got the gun to his shoulder it went off. The elk was running and jumping over logs, and I heard Noah talking to himself, though he was across the creek from me. He says, "Oh, Oh! I, er, well its all right, I killed him anyway." The bullet had hit the elk and killed it!

From Stories passed down from my Grandfather, Noah H. Hudson - by daughter Lela Hudson Darst, mother of Calvin Darst.

Uncle Joe was quite a hand to talk to himself, his horse, or whatever he was working with. He had a Remington Rolling Block Rifle that would sometimes misfire if the shells were not sized down right. One day papa [Noah] and Uncle Joe were stalking some elk up a small creek that had a lot of willows in it. Papa was on one side and Uncle Joe on the other. They could not see each other, but papa heard Uncle Joe say to his rifle, "You miserable thing, won't go off when I want you to." --then a little later, "Well I guess its all right, you killed an elk. He had the gun down working on it, trying to get it to fire, and it did. Without any aim, it had hit a nice elk and killed it!
