AKA
La Señora Miniver (Spain)
Madame Miniver (France)

1.- Bentley Convertible 3 1/2 litre??? 3***
I'm in a doubt.
Looking this logo of the car, I think is a Bentley (with covered headlights)

But it isn't with the typical figure in front part


All next pics, backgrounds 1*
2.- English Bus AEC??

3.- Taxi on the left

4.- Van (black and white) on the top and also car stopped in front of the van

5.- Probably Rolls or Hispano??

6.- Bikes with side-car

Probably the same bike than this one (down at left. Only partial view)

Mrs Miniver was made by MGM in Hollywood. The bus is definitely a fake built using a real American bus - you can see a passenger door on the right, just behind the front wheel.

SteveA's site, Buses on Screen, has an entry for Mrs Miniver, where you can see that the bus has been given an open platform on the left at the back.

Good link.
I fell for it. Now I get it. Thanks.

Done! Interesting cars in this movie.
