"
Instructions for Use with the 200 Gallon Water Tank Truck Chevrolet and Dodge T 222
and 350 Gallon Water Tank Truck, General Motors,
and 180 Gallon Water Tank Trailer
Published by The Chief of the General Staff, Canada
1943
A 50 page booklet aimed at army drivers with instructions on how to use these water tank trucks which carried drinking water during WW2. There is a lot of stress on how to sterilise the water. Illustrated with a few good black and white photos and detailed drawings of the engine and other parts."
I've copied it here just so you know this manual exists.
