content: The engine drawings consist of sketches, calculations, repair parts orders, drafting room specifications, contract orders and construction blueprints. The engines were designed and built for a variety of clients.  For example, Engine #241 was designed, built and installed at the Amesbury Electric Light Company in Amesbury, Massachusetts. Many of the construction blueprints are annotated with the engine number and other notes about installation. The drawings are 24" x 36" or smaller and are folded. Indices for the drawings consist of 3" x 5" index cards.  The cards contain a drawing number, descriptive title, and in som instances, additional notes.   For example, drawing M-1339, crank pin effort, connecting rod=5 cranks long. The series is arranged numerically by engine number and is not complete.
