Ferrari Formula 1 Wheel?

Found an intereasting offer in eBay Germany and need experts opinion: on offer is a Ferrari1 F1 wheel apparently from either Alboreto's or Johansson's 156/85 car as driven in the 1985 Monte Carlo F1 Grand Prix. Can this be authentic and, if so, what would it be worth?

Thanks!
