I'm British, a farmer's child, and I'd not buy another.
Sorry--there are better modern fabrics that can keep you warm and dry and don't have that insanitary component to them. Of course they lack a certain hairy, public school, fear of underarm deodorant, Hooray Henry quality, but I've found I can survive quite nicely on my ranch without the requirement to go round smelling like a dead rat.
Hot running water is no longer a rarity, even in the wilder parts of Britain, so washing one's clothes is no longer a luxury or an indication of softness.
However, many years ago when I was a student out in the wilds of Norfolk, my then boyfriend decided that the best way to finish off the re-proofing process on his Barbour was to put it in the Aga. Unfortunately, he promptly went to the pub and forgot all about it. You have never, ever smelt anything quite like what greeted us upon waking the following morning.
