Er ... you're supposed to read the title, Steve
When marcus says he saw the end of this "WW2 George Formby", he means the George Formby film (or, for you, "movie") called "Spare a Copper".
[In case it doesn't translate into American, the title is a pun, on the phrase "spare a copper?" used by beggars, asking for some small (copper) coin, but also covering the role George plays, as a copper (as in policeman) who gets into trouble. Yes, well ... not one of George's best films!]
I guess marcus didn't include a link, because he didn't know one (having just seen the film on the TV).
I don't know what the car is, but you can see a bit of it in a not-very-clear pic on the GeorgeFormby.co.uk website:
