Here are Nardi and Hellebore in confrontation. Though similar, they were different in shape when produced for the same model of the car. Nardi had slightly wider rim and bigger holes on the pokes. It had usually six holes hubs and was not fixed on AR GTA as factory equipment. Hellebore were officially 38 cm diameter, though you could measure 39 or 37,5 cm as well. (They were hand made, and that explains the differences). Sometimes you could observe small differences among series. Initially, commercialized by V. Gallino, they were signed V.G. Hellebore, later only Hellebore. Both Nardi and Hellebore were small factories from Turin, suppliers of exclusive steering wheels for Italian sports car industry (Ferrari, Maserati, Lamborghini, Alfa Romeo and so on). Founder and owner of Hellebore, Luciano Maestri, had his production in Berra (Serravalle) near Turin and his wheels were used for Abarth, Alfa Romeo Cooper, Lamborghini (Miura), and as aftermarket pieces, for many other models of European production.
