is there anybody knows this Cobra ?

The chassis number is stamped on the left 4" round tube just behind the lower A-Arm support. Turn wheels to the right, and look under the car behind the tire for a stamped number there. Maybe it is covered by paint and you have to scrape it clear. From that frame number it can be deducted when the car was build or sold, although no exact records exist because of the extinct manufacturer company. Most Contemporary Cobras were build in the 80's and early 90's
The number you mention does not belong to any Cobra manufacturer and has been probably been made up.
The title shows the year of the Cobra, which should be 1965. Many States took the engine build date as the build date for the whole car. The engine of the Cobra on the pictures is a Ford Big Block from the 60's.
The other date on the title is the issue date to the last owner. Since the car could have been sold several times that date does not determine the build date. All proof you have is that date on the title. It should be enough for the french authorities.
