Enlarged & Revised Edition. The handguns produced by Colt’s Patent Fire Arms Manufacturing Company have been the object of serious historical research for many years. The rich historical tradition and great commercial popularity of Colt handguns has made the Colt an integral part of the subject matter comprising the history of mechanical arts in the United States. Direct study of fine collections of Colt arms throughout the country form the basis of this book. Sixty years of research, engineering and production development have produced so many forms and designs in many calibers it is impossible to collect a complete history without “blind” spots or gaps, despite the availability of good specimen collections and fine reference materials. For the author, every new fact brought the realization of other facts still to be learned _ a never ending process. The text of this book, therefore, contains two types of information, the “Factual” and the “Speculative.” Soft cover, 6″ x 9″ format, 354 pages. Illustrated. Index.
