And a blast from the past, when I first started collecting ww2 brit airborne ca 1976, I bought original ww2 dated denison smockes for 30-$40 each, the windproof trousers for $10 ea and the ok oversmock the paras wore (they wore this over the denison smock to stuff gear in during a jump for $8!!!!! Ahhhhh the days before repros. I thought I was doing great to sell them at double what I paid for em!! If I had them all now!
I think you're right Steve, I suspect the brits made groundsheets out of this material, and much easier for an indochina tailor to model up custom garments from them! It's always cool to see the French troops wearing surplus hbt fatiques with the USMC logo still in place in the middle of indo ca. 1950!
