1954 Cadillac Pininfarina 3-seat roadster

I saw this car painted blue at Pebble but wonder if it was the same one driven by

the King of Belgium in the Fifties that went off the road. There were two of them built

so I am trying to find out, for historical purposes, if the one Harry Yeaggy owns and was displayed at Pebble is the same car

slightly restyled when rebuilt with the addition of Ferrari Superamerica style side vents.
