Cord 810?

Far from the first. Lancia patented their version in the 1920’s. Some debate on whether earlier cars ( Lanchester, Ruler) had true unibodies.

The hardtop Caribbean is 56 only. Compared to a 400, they have a painted side band instead of the ribbed metal trim, and white padded top ( I think Hypalon originally). Inside, they have reversible seat cushions. Fabric on one side, leather on the other.

France went to driving on the right in 1794

Straight side molding is correct when the two tone body wasn’t chosen. I think the gold engine paint is supposed to be silver. Handsome car.

The block letters are 46-48. The latter photo with the lower case letters is 41. I don’t know what was used in 42. I once bought a 41 with multiple style caps on it so had to sort out what belonged

No price = no interest

France had amber high and low for many years. Near the docks in LeHavre you would beware oncoming white headlights - it was Brits off the ferry and not always used to driving on the right

39-40 the 41 has lettering on it

Ultrasound is an interesting idea. Your friendly local jeweler often has one for cleaning rings

The wax-lined bottle makes me think hydrogen peroxide is part of the formula. It doesn’t attack the glass but the glass content degrades it

Optical brighteners for fabrics and plastics are completely different chemicals and purposes

This is the best idea. To be clear, this does not mean « a tire that has Michelin molded on the sides ». Old molds can be sold to people like Coker. It means the company. They have the rubber mixing equipment to make a gray batch

It sounds like your version is also based on zinc chloride

There are three issues. First the paint would need to be as flexible as the rubber. Second, it’s unlikely to be as abrasion resistant as the rubber compound. Last, the paint’s solvent needs to attack the rubber enough to promote bonding but not so much as to damage the tire. The dingy paint sounds interesting, but be prepared for frequent touch -ups. I would try to contact the paint manufacturer for a technical discussion
