Under the guidance of mainly "Frank" Baughman during the early phases of firearms training, assistance was offered - secured - to and by the Bureau from multiple sources to include representatives from the major firearms companies of the day.
This particular document from files reveals the interest the Bureau had in the training and teachings of Colt Firearms representative, John Henry Fitzgerald. With his reliability established he offered unique training in, among other areas, right and left hand shooting, quick draw and silhouette targets as opposed to standard targets.
According to information from Amazon.com, where readers can buy his book, "Shooting"...
"John Henry ("Fitz") FitzGerald worked for Colt from 1918 till 1944. Shooting, originally published in 1930, was the culmination of Fitz's work in the firearms field. In it he discusses his work with law enforcement and the courts, his theories and practices about practical shooting of the "one hand gun" and his thoughts about target and exhibition shooting, hunting and home defense. This was the only book FitzGerald ever wrote, but his life was clearly dedicated to all aspects of handgun shooting. While his written work might be unfamiliar to some of you, those who are reading this work for the first time should be very familiar with the writings of Elmer Keith, Charles Askins Jr., Ashley Haines and Chauncey Thomas. All these men were friends of FitzGerald and thought highly of his methods and approach. After reading this book, you will feel the same way. Paladin is pleased to add this long-out-of-print volume by one of America's most renowned and colorful shooters to its Combat Classics library. The new forewords by FitzGerald scholars Timothy J. Mullin and Kevin Williams, as well as the addition of a number of never-before published photos, shed new light on FitzGerald the man and the shooter."
