I don't know the year (I didn't take that down)...It has a model name that isn't really related to a race.
Sometimes referred to as the Model X, but I think that's a post hoc name.
It is a well-known car here, owned for many years by Sir John Briscoe (who called it "Denise")and may still be in that family.
There was a long piece on the history, finding and restoring the car by John (Lord) Charnwood in the VSCC Bulletin in Autumn 1952
These cars finished 1, 3 and 4 in the Coupe de l'Auto and this was the winner (driven by Bablot)
