Drawing, Technical

One drawing that shows two views of engine components. The drawing consists of black pencil on heavy paper and shows:
1. Left side of sheet: front end view of engine.
2. Right side of sheet: side view of front portion of engine.
Several parts are noted on the drawing, but the views were only partially completed. A handwritten note in black pencil at the lower right corner of the sheet shows "JSB [James Scripps Booth], started 9-16-21" and "Front end of JSB 4 cyl. motor when chain drive to lower level propeller shaft is installed behind the flywheel - See other drawings, JSB."
