Call me a suspicious Simon, but I think we have a scam artist at work here. The listing has lifted image and description straight from Vectis' website from their 28th Nov auction. Hopefully it's a just a case of someone selling the lot that they won and being lazy with the listing's specifics. But their selling record seems to be more of a market trader/business type.
