D50R

The D50R was a short run of recreations of Lancia's Formula 1 car, made with original engines by Guido Rosani in Turin. Guido was the last direct link back to the factory race team - his father had been the architect for the Lancia company, and young GUido (at about age 10 or 12) spent some of his youth running down the aisles in between the drafting boards. He knew Lancia history better than anyone else.
I was lucky to spend time with Guido while visiting Torino and working on the De Virgilio book. Guido appreciated my love of the drawings (he was a skilled draftsman himself as well as fabricator), and wanted his picture taken by his drawing board. We looked at the drawings from the 1950s, from the B110, D20, D24 and D50s, all of them, over the years. He shared with me a book on his father Gino Rosani, privately published by Pininfarina in his honor. Gino had worked closely with Gio Ponti on the Lancia building, a very interesting 1950s design.
This picture of the D50 construction is of the front suspension, with double wishbones ,  a lower transverse leaf spring and remote dampers. It was taken by Nigel Trow, another good friend of Rosani's, as Nigel had the chance to watch the cars be made. He wasn't the only one - one day Gianni Lancia came into Rosani's workshop, to check on his projects as well.
Rosani made both D24 and D50 cars - only using original engines, but making much of the rest up, with help from many in the industry who were familiar with the cars. The D24 lines were partially penned by Ercole Spada, formerly of Zagato, now retired - another one from Guido's deep Torinese network.
The cars were made meticulously, with even the rivets in the gas tank per the factory drawings, where no one would ever see them. He was quite proud that he followed the drawings carefully.
There has been discussion (especially in the British press) as to how much was done by Rosani, and how much by Jim Stokes, who fettled the cars once done. While Stoke's work was invaluable and very well done, the real construction was in Torino, as shots like this make clear. 

Here is a later shot of the D50 front suspension which I took of the D50 in the Revs collection in Florida. Just lovely workmanship.
