I have a couple of Dave Duffey books I don't really need. They are written back in the mid 70's. Not the best of shape. Books are:
Expert Advice on Gun Dog Training, David Michael Duffey, Winchester Press, 1977
Dave Duffey Trains Gun Dogs, Sporting Dog Specialties, Inc.,1974 pretty beat up.
Don't remember how much I paid for them but you can have them for $5 + shipping for both. Email me at
[email protected] if you're interested.
