Yes, I also have the Traction Numbers book. Very interesting and from the information in the book I’m fairly certain my car was built in June 1953. I also know the plate number of my car when it was in France and I have the owners name at the time of the sale of the car (probably in the mid 1980s). It would be interesting to know who all owned my car from 1953 onward in France or if the person listed on the sales document was the original owner.
