I have seen this carb on ebay a couple of times and wondered why nobody had snapped it up. It appears to be suitable for the very early models but not sure if it will fit later ones. This carb appears to have a water heated base so if somebody were to buy it for a later model I feel that they would have a few headaches in trying to adapt it. I would buy it anyway and put it on the mantlepiece for showing off, as someone will be desperate for one of these one day!!
