Sorry D-type, but oko94 gets the point. He has found the full original image, complete with enough to answer the question.
It was built in 1949 by Fourny (I have seen this spelled as Foury) and I can find only two race entries for the car - on 27.8.49 at the II Prix du Leman at Lausanne, raced by Pierre Nessi, where it did not start, and on 7.5.50 at the GP de Cinquantenaire at Roubaix, driven by Max Foury (that spelling again) where it lasted just 3 laps.
Both races were run to Formula 2 regulations, so it was a sort of French equivalent of the Cooper-JAP 1100 cars run by the British in these events. The engine strictly speaking was an HRD because the Vincent name wasn't adopted until 1950.
I am not sure when the car was restored, but parts of what looks very much like this car were on sale at an Autojumble, and the vendor thought they were from the Hardy Special,(not the UK car) run by Camille Hardy in French F3 events, but the dates don't fit, Hardy drving his car earlier in 1950. If I can find the relative photos, I will post them.
