Market Hunter, is the book you refer to Chesapeake Bay Retrievers, Decoys & Long Guns? If so I have a copy because I own a couple of Chesapeakes; also interesting because of the shooting in that period.

I own a shoot a double 8 by Joseph Lang. A great goose gun but not one that you would want to carry too far. They are spot on for geese in the 50 to 55 yard range. Lagopus.....
