Captain Charles Askins (Askins the Elder) wrote some good stuff on shotguns and bird hunting as well. If you can find a copy of his 1931 book GAME BIRD SHOOTING it not only has a lot to say about shotguns, dogs, etc. but is great look at what upland bird hunting and waterfowling was like in America during the early 20th century.
