Thanks for all those wonderful responses and feedback...Little Ealing School..didn't they have an open day in recent times celebrating 100 years..I think Penny Crocker went there.
Loved the story of the little cashier's cubicle..very hygenic wasn't it? I believe there's still such an example today at a butchers in Crown Road St Margarets. (check street view Tony?!).
What a road..Enfield Road. Here's the full view of Peter Downes postcard....in GILLIAN CLEGG'S PUB BOOK...in which one can see Fran's greengrocery shop. Look no cars. Children can play in the street. Kick the worn out tennis ball up and down the road...bouncing it off the kerbstone.
