Machine gun belts from 'waste material'

I found this report in the minutes of the British Ordnance Board, its dated June 1939.

To me it all sounds highly improbable, does anyone have a clue to whether there’s any truth to it?

Happy collecting, Peter

I see no reason to doubt that it’s possible. Here in the U.S.A. we made a POTUS out of a sow’s ear about 3 1/2 years ago. :(

Maxim belts were also made using fibres from nettles.
