What car is this?
 

If you can see the picture on facebook, what car it is?

I don't know.
The single headlight looks very strange. Just searching online, the grille and sides of the hood look similar to an American Plymouth, but of course this one has right-hand drive.

Unfortunately, a lot of cars in the 30s and 40s looked the same. Clearly it's in the UK, but yeah, it does look a lot like a Plymouth, or at the very least, an American car. The thing is that most English and European cars were tiny little things. Not the size of the car pictured. Excepting high end cars like Rolls and Bentley. It would not have been that strange to have an American car imported to the UK in those days.

Some American car makers like Ford had UK/Europe divisions/assembly plants. It's possible it is a Europe only model customized off of an American body and chassis.

The body looks like one of the Mopar brands but the grille looks more like GM (Buick, Pontiac).

Don't think I've seen a factory US car with a single headlight from factory like that...I think we had some kind of dual headlight law for cars by 1920.

Oops duplicate post.

This site gives history of Chrysler/Plymouth/Dodge exports to the UK (apparently built in US and Canada as right-hand drive), but unfortunately no pictures from the 1930s:

Edit: on re-reading, it's not clear to me if only stampings/parts were exported at that time and then assembled as right-hand drive in the UK. Farther down the page, it seems more clear that this was done in the 60s.
