Love that Hanson's dairy one.
As a kid down Melwood back in the late 50's and into the early 60's, we used to get our milk delivered by Hanson's.
I could well be wrong, but didn't they have a depot Cantril Farm way?
I think the milkman we had was called Frank, and he was a big man, built like a butcher, or certainly seemed like a man mountain to me as a child.
He would toddle round the estate on foot all on his own on a Friday evening with a leather satchel over his shoulder collecting the money due.
I was led to believe that one evening, a couple of characters decided they'd attempt to relieve him of the money and the story went that he put them in hospital, which was entirely believable.
He then seemed to start coming round with another fellow, I assume for deterrence and backup if needed.
