I just bought this for the princely sum of £20, a Mk1 or Mk2 porky. Only issue that I have found so far (other than a slightly ratty hood top) is that one of the vertical cage rods has snapped at the top of the thread. The rod screws directly into a boss in the tank therefore this is a problem. Does anyone have either a spare threaded cage rod (probably stored behind the Unicorn horns in your flying pig hangar) or know what the thread is on these? I don't want to inflict JB Weld, superglue or solder if I don't have to. I usually hang my lamps from a beam in my garage but the cage is significantly weakened by having one leg "in the air" and don't trust it. As the early preheaters sell for an eye-watering amount on ebay I view it as buying a preheater with a free lamp thrown in Paul.
