Another Walsh book is "The Outlaw Gunner" Punt guns, lights, traps, and lots of other ways to harvest ducks

2 different books and authors, I'm not sure if they are related.
Roy E Walsh wrote "Gunning the Chesapeake" in 1960
Dr Harry M Walsh Wrote "The outlaw Gunner" in 1971.He was the man whom with some others was instrumental in the creation of the Waterfowl festival.
His son made a second printing of the book last year or so with some added content that was not previously published.
His son Joe had a great display of some of the artifacts shown in the book at the festival this year.
