As noted,, there are (2) different dust jackets. The one with the antelope & the cut-away of the SA is the first one,, while the second one shows the colage of stuff.
And no,, there isn't a later or second edition.
BUT,, if you seek really good info on Rugers,, and want to expand your library of books, I suggest John Dougan & Don Findley.
Both have some books out that are a WEALTH of knowledge. Don has some books out that delve into the family history of both Bill & Alex. John has a book out that's a very, very definitive research of the guns.
Bill Sr. designed & built (2) cars, a yacht, & all kinds of other items. Valuable history & luckily, pretty well recorded.
