I also saw one at Kempton Park autojumble yesterday. It was fixed to a box section rear number plate on a swing arm pale blue Golden Flash that had been brought back from the States and the dealer had up for sale. I talked to him about it and during the conversation he said he had a number more back at home. I suggested he thought about selling some so he may have them on his stall at the next autojumble in April though he didn't really say.
