The notes and sketches are largely in the hand of Lanchester and arranged chronologically, with sections by George Herbert Lanchester and Sidney Pinsent, Chief Draughtsman. Probably used at the Armourer Mills works, Montgomery Street, Sparkbrook, Birmingham. The notebook starts on page 5.

Each seciton has been divided after the fact, possibly by George Lanchester.
