Hahahaha lots of misunderstanding In here I reckon!
A "canvas" poncho? Isn't that a bit atiquated for Faulands era issue?
No, Dave53 has a Canvas poncho ROLL as issued as part of the 58 pattern webbing, like this,
Its the rectangle on the right above the belt, used to hold the rolled 58 era poncho\shelter like this, clipped on below the webbing,
Excellent kit, if only it didnt soak up every last drop of moisture on the planet,
the poncho looked like this,
All though some cotton ones were issued,
But only if you had the legs for them
