An original Ferrari Gestione Sportiva factory engineering drawing for the front hub bearing retaining pin (Perno fissaggio cuscinetto al mozzo anteriore) developed for the F110A Formula One programme, dated 14 March 1984. Produced at a 1:1 scale, the drawing measures approximately 42 × 29 cm and is printed on original Ferrari watermarked technical paper. The title block identifies the component as a retaining pin for the front hub assembly, manufactured from 38NiCrMo4 alloy steel, for Tipo F110A3100, Ferrari drawing number 124509.

The drawing originates directly from the estate of Renzo Medici, who joined Ferrari in 1947 and spent almost four decades with the company, ultimately serving as Head of Parts Production in Reparto Corse. Preserved within his personal archive after retirement, it represents an authentic working document from Ferrari's Formula One engineering department and provides a rare insight into the meticulous design and manufacture of even the smallest components within the Scuderia's Grand Prix programme.
