Hi Frothy,Ive just spoken to my Sister who used to live with my Mom and her Dad in Bromford lane alongside our Granddad and she has never heard of it either, she said she used to go to Stratford Rd to Roller skate and our Mom never mentioned it either. So I cant help you I'm afraid. try Carl Chinn.
If you have lived in Erdington all your life I bet you'd have known my Grandad. He lived in the house on Bromford Lane, next to the shops on the Crn of Erdington Hall rd. His name was Fredrick Hopkins, he was a pot man at the Navi and The Green Man too and also laid the bowling green at The Lad/Green Man.
He also raced and bred pigeons and was one of the top fanciers in the Midlands.
He died in 1962 aged72.
