Clyde Baker's Modern Gunsmithing, a Revision of the Classic by John E Traister

598 pages.  Very good hardcover in a very good dustjacket, clean unmarked text block.  Whether you are just 'tinkering' or into a serious project, very goo advice.  Traister operated a gun repair shop and has written over 200 articles and over 30 books on the subject.  Mailing anywhere for $18, combined mailing with other books or items in my listings.
