These collectors models are not based on a real Rolls-Royce because the original donar model was a Fiat. Eligor designed a rolls-royce grille, bumper and wheels set just to add to the casting to make a rolls-royce car and the nearest car in the size to scale ratio is the late 1920's 20-25 H.P. chassis. This has nothing to do with the Phantom I car shown in the original title.
