You must of got my e-mail by now but I have a personal hub for a 280SL it should fit a Nardi Wheel I can fine out from my auto accessorie guy next week if you like and send you photos. It is in nice shape and If I remember correctly my car hada leahter Nardi wheel on it wwhen I got it. I sold the wheel so I suspect this is the hub that it was attached to. I also have a new horn button with the star but I am not certain if it is in chrome or black.
