I had one of those as an Army cadet in 1957 at Camp Borden, Cadet Trades Training Camp, D&M.

It was a great reference manual since our hands on involved 15 cwt "strips", which were Chev/Ford CMPs stripped right down to chassis, seat, steering wheel.

IIRC, the paths of flow were shown in different colours of paint so that a student could follow the hydraulic, fuel, water etc lines from start to finish.

Thanks, Keith for a pleasant memory flashback!
