12467 is an important car in Ferrari History if Chinetti commissioned it too. He was Ferrari's partner in the US and the Official Ferrari Importer so in my opinion the mods can be considered genuine Ferrari as they were commissioned by a Ferrari agent - N.A.R.T. no less, and carried out by Diena & Silingardi, Sport - Auto, Modena who did much work for the Ferrari Factory. It was certainly the N.A.R.T. Daytona Competizione Prototype, the style of which the Factory also followed in the series of Comp Daytonas they made. Both the N.A.R.T. and Factory Daytona Competizione cars are absolutely awesome!!!!
