This is a rare Ace wheel disc, used to cover the vulgar wire spokes on the wheels of certain quality British cars, including Rolls-Royces, Bentleys, Alvises, Daimlers, Jaguar SS and Mark IV, and others. This one is a little dented but not too bad, and the chrome is even fairly presentable. We do not have any other parts apart from what you see in the pictures. We have tried to show the major defects in the pictures. It is about 19 inches across.
