my dad built the blacksmiths forge there. thats what he was in the rafNot Vincent related (although I do own a couple), but while working on Duxford airfield I was asked to find out why the petrol bowser, used for filling the flying exhibits, emitted showers of sparks from the exhaust when running the pump, Found the culprit to be a decomposing rabbit inside the air filter UPSTREAM of the paper element, and no, I have no idea how it got in there.
