I own two volumes, Vol I, August 1985 and Vol. II, June 1987.
Vol. I is a lengthy article by Gary Brumfield all about flintlock design and lock making; The Production of Flintlocks Used on Colonial American Rifles: Raw Materials, Tools, and Technology. It is a step by step description, with photographs, of the process of forging a complete lock, by hand, from wrought iron. Also shown are some tools that were used, like tumbler mills, screw plates and taps and a screw grinder. The locks shown in the photos and illustrations all look like large Silers.
Volume II has five articles. The titles are pretty self-explanatory;
