WW2 Canvas Material

[David Dunlop]

Was there a standard weight of canvas used with Commonwealth military equipment, or did the weight vary with intended use?

I know there is a difference between standard canvas and canvas duck, where the canvas duck has the same weave pattern in both directions, making it stronger and more tear resistant, and heavier weights would wear better than lighter.

The Waterproof Curtain used on the front of the Wireless Set No. 52 is canvas duck and according to the Parts Lists was Olive Green, which is a lot lighter than Olive Drab, but no weight reference is provided. It is unlikely it would be the heaviest weight as used on a CMP cargo tarp and I am thinking possibly a weight close to seat cover weight, or slightly heavier.

Were weight reference charts for canvas products ever produced, I wonder?
