hello
if you look at your map you will see a gap between the shops, there was a greengrocers on the corner i think next to Webbs, although i am talking about the 50s so webbs may not have been there then.
in that gap was the entrance to what was eventually archbishop ilselys school but there were some huts on part of the site behind were webbs would have been and it was an annexe to Holy Souls, the school i went to. Holy Souls was further up the green.
whats your interest in Webbs if they were there in the coronation year there is a good chance we had our first tv from there!
