Commenti

  1. COMPLIMENTI e molte felicitazioni: tanto rara quanto bella, anche tutta originale ha un fascino veramente innegabile.
    Che progetti avete per questo gioiello?

  2. Ciao Arturo, grazie, restauro conservativo, sostanzialmente resterà (anzi tornerà...) come era in origine, contiamo di aggiornarla solo con l'accensione elettronica ed un manubrio più sportivo, per il resto configurazione standard
