Model Ferrari Dino 156 F1 Sharknose CMC 1:18 is available in 4 variants ow which 3 have racing numbers on car body. Models differ by car body and wind shield details. For me the nicest one in this aspect was number the one with racing number. But I did not liked transparent plastic covers over the engine, so I swap them to metal mesh and also removed racing number from the car body.
