"A Study of the Colt SAA Revolver" by Graham Kopec and Moore is the book on 1st gen Colt SAA's. I'm not sure if it is still in print. No Colt collector, no matter what he/she collects should be without Larry Wilson's, "Book of Colt Firearms", it covers everything including the SAA. Want a good coffee table book with great pictures, "Colt, An American Legend", another Wilson book. Happy reading.
