Spotted this postcard for sale. At first glance it's a B20 (on whitewall tyres).
But is it?
To start with, it looks too big, doesn't it? And look at the badge on the front wing; the door handle... Is that a chrome strip on top of the door? Is the rear window shape correct (the rear profile looks a little too circular to my eye)?
Experts please contribute. I think it might be a B50 (see second photo)
