The 1/2-inch thick, 124-page Blue Book of Colt Dates of Manufacture, a landmark and comprehensive reference work of great value to collectors, dealers, arms enthusiasts and law enforcement agencies and personnel, worldwide. Based on Wilson's The Book of Colt Firearms and tables in his official histories of Colt firearms, as well as on fresh research principally by Kathleen Hoyt, Colt Historian, this new volume is the last word on the subject. Including a foreword by Wilson, remembering his initial visit to the Colt factory, 1959, when in Hartford to be interviewed for a position as a summer intern (1960) at the Wadsworth Atheneum museum of art.  That visit led to his eventual appointment - at the age of 23 - as Curator of Firearms at the Atheneum, and to publication of two of his earliest book titles, Samuel Colt Presents A Loan Exhibition of Percussion Colt Revolvers and The Arms Collection of Colonel Colt. The Blue Book includes a detailed index, and a color cover inspired by The Book of Colt Firearms 3rd edition.
