Answer: Don't know what it was like in the forties, but we were there in 2010. Wonderful place to visit. So animated. Not only were their vendors, but there were Street entertainers as well. What I found amusing was before you get to the part of Portobello Road where there were these vendors, you had to go past the stately homes with gated grounds. Expensive cars with pull into the drives. Wouldn't happen here in the United States.
