Thought of you today when I was fiddling with oxygen cylinders (massive ones).. If you were very very ill (or pretended to be) you could get your own, with its own little trolley thing.. then just run off with a the gown flapping in the wind and your hairy arse displayed for all to see.
Also.. just how much mz stuff do you still have laying around? I'm considering fixing up the one I have for some poor fool on ebay (or just getting the engine running and selling a rolling frame and keeping the spare engine for minimal titting about)
