Great knowledge... Many thanks,
If it helps, my sister gave me this additional info:
The Maypole Dairy (the shop with the awning just behind the tram) was number 90 Hight Street, the next shop on the right was called Colliers and next right after that was the Palace Cinema.
If you went down the alley between Colliers and The Palace Cinema you came out the other end with Mason Road on your left.
Our flat apparently went above both the Maypole Dairy & Colliers. My sister's bedroom window was over the alley to the cinema and she could hear the film music through the walls!... This incidentally, was the room I was born in.
We left the High Street in 1961 when I was a 1 year old, I remember a few years later (mid 60's), my Father driving us through Erdington and saying to me "Just around this corner is the house where you were born son"... We drove into High Street only to find a huge pile of bricks & rubble... They'd knocked it down the day before!!
I think that this bit of the High Street is pedestrianised today, although I have not been there since the mid 80's so I can't be too sure, but I seem to remember that back in the 80's there was a supermarket (possibly a Tesco) near to the site of number 90... Although I could be wrong!!
Here's another view of the Palace Cinema from 1951
