Does somebody have any idea of the value of the following manuals:

-Tanks Cruiser RAM I & II, Instruction Book, 1942, Illustrated,
come with a Storage Chart and Lubrication Chart.

-Valentine Tank VI & VII, Instruction Book, 1942, Illustrated,
come with 13 8X10 glossy photos of the tank, Lubrication Chart
and 2 Hull Wiring Diagram.

-Valentine Tank VII Illustrated Parts List, 1942.

Published by authority of Department of National Defence, Ottawa, Ontario and Tank Production Branch Department of Munitions and Supply, Ottawa, Ontario in 1942. All in excellent condition. Thanks.
