Classic Cars Certificate of Conformity

I have a classic car and one of the requirements to register the car here is a Certificate of Conformity. Does anyone know if it is required for classic cars. The car in question is a 1949 Citroen Traction 15 Six.

have a look at this. You don't need an Attestation de conformité but you do need some other documentation.

Apparently so. Or should I say, there are garages appearing that offer this service. Of course they seem to be adapted to the age of the vehicle. We also have had to take out classic car insurance which apparently puts them in a special category.

Nice looking Citroen by the way
