Alas Pete Truman won’t be responding to your question, as he incurred a life ban from one of the moderators, who coincidently has been instrumental in overturning a “life” ban for at least one current forum member; I guess it’s as they say ,”not what you know, but who you know”

Thank you. If I ever discover the Finchingfield location I will post it.
For what it’s worth there was an AWT on the corner of Chapel Hill and Clockhouse Way in Braintree when I was a boy in the 1950s. it must have been dismantled in the 60s.
