The van in the picture is a Ford Anglia 10cwt Van. They were very popular delivery vans, light cheap and easy to drive plus easy to maintain.
I can see the van but no idea if it is a Ford Escort or not… surely they were invented in the 1970’s though??
Can’t see an Escort van in this picture – perhaps it hadn’t been invented at this point in time…
