Lloyd,
I have heard that a few of the US helicopter pilots in Viet Nam cut the butt stock and barrels from Darnes obtained locally, to use as "last ditch" type weapons. I've been told the story more than once over the years, and being that 'Nam was a French colony, a Darne might have been more frequently encountered than any thing else.
Jihadi John is a product of England, it would seem to me that the English have more important things to worry about than what country produced a TV murder weapon.
Best,
Ted
