The Book of Colt Firearms by R. Q. Sutherland and R. L. Wilson, published in 1971. There were two editions of this book; the hard cover edition and the leather bound edition with slipcase that were numbered 1 through 500. This particular book is SERIAL # 1, RQ's personal book! The book and slipcover remain in nearly perfect condition after 40 years. Provenance for the book comes in the form of a personal letter from one of RQ's children authenticating that his book sat on the desk in RQ's gun room/vault until his passing. This is the ultimate collectible book on Colt firearms. The RQ book was regarded from many years as the definitive reference book on Colt collecting. Subject to prior sale.
