Water butt (City of Bristol BS16)

I recently asked for a stand for a water butt which I've inherited on my new allotment. I was kindly given two, so now I'm after a water butt for the spare, so I can have two working water butts. I need a 200 litre one, which is the standard large size one, not the slimline. If anyone has one hanging about , I'd be very grateful;.
