Well, I suppose you're talking about the 402.
But can it be online sources are talking about the same car, one time it's 302 based, another time it's the 402 based?
I found a picture online which shows the type (302) and chassis nr (761261), and on the same website I saw the same picture as in this puzzle.
Funny thing is, I saw this car in the flesh a couple of years ago in Chimay, even took some pictures
