I read a lot of fiction, sometimes I think too much. I’m always on the lookout for books about guns and gunsmiths when written by knowledgeable people. A few of my favorites are,
Gerald Hammond, writes about Keith Calder a Scottish gunsmith who not only collects but shoots. The books are a wonderful look into the sporting field there. There are about twenty or so of them and I highly recommend any but start with “The Reward Game” 1980. Mr. Hammond posted a few times on the old doublegun board but I don’t think that anyone recognized him.
Donald Hamilton, yes the author of Matt Helm which I confess to reading all of them. He wrote one book about a Gunsmith ‘Line of Fire” Gold Metal Books 1955. Donald Hamilton wrote a few articles in gun magazines and knew his way around firearms.
Jonathan Gash, writes about a English antique dealer and collector named Lovejoy he must have written over twenty books but the one I like the best is “The Judas Pair” story is about a set of Wodgon pistols.
