In January of 2012 the following note was received from James Kelly, 514 Harrison Street, Rochester, Michigan 48307-1916, firstname.lastname@example.org: Another gentleman and I have written a book, Michigan Gunsmiths, covering guns made in Michigan from the late 18th through the early 20th centuries. During research on Dr. W.H. Barnum I found your name. The Doctor's part in this subject was that he bought the last, or surely one of the last, muzzle-loading rifles made in Michigan by a professional gunsmith. I have attached the section on the gunmaker, Lindberg, written for this edition.
I would like to write an article on Lindberg's Sons Managers, and include something on Dr. Barnum as, probably, their last customer for a muzzle loading rifle. In 1943 the sport of muzzle loading rifle competition was just beginning to grow. It would be interesting to know whether Dr. Barnum intended to compete with this rifle, or just liked the idea. Again, in 1943 wartime needs meant it was very difficult to get cartridges for one's hunting rifle. It was still easy to come by percussion caps and black gunpowder for a muzzle-loader, though.
