DT Fletcher Publisher
DT Fletcher is an author and publisher of many vintage airgun books.
I just received my copy of DT's book on the Crosman 600. It's a very good book for any 600 owner. I'll be adding more of his books to my collection.
Here's a few examples of DT's other books.
To see all of airgun publications visit his vintage airgun store.
