No, it's not a Peugeot..
Yes it is, because it's the prototype of the 10 CV Peugeot 502 of 1939, registered 6504EK2
This prototype was intended to replace the Peugeot 402, but the war has decided otherwise
Well fancy that..!
The 'Site I got the picture from described it as something completely different, but I can see why having found their source..
I have been unable to find a picture of the car you describe anywhere else but you do seem to have full info on it so I'll give you a point for its correct ID, although it's not what I thought it was! Hopefully it's not a repost..
So that I can verify that what I'm describing the car as is in fact correct would you be able to point me towards some further info on this prototype, either by posting it yourself or PM'ing me where I might find it?
Thanks.
And sorry qwaszx for giving you an incorrect answer, but that was based on the info I had at the time; unfortunately I can't give you a point because you didn't give the correct ID in the end.
