Thanks to all the people who have replied in the past few days, to be honest I had not checked this thread for a long time.
There is some new information for which I am very grateful, and to add a little more. On my Dad's birth certificate which I now have, Stanley is listed as a member of the MGC, but in India. I knew nothing about the tank corps, but my Dad also joined a tank regiment in WWII. (The 15th/19th Hussars).
The address near Claypole is relevant too, his parents in law lived in a house nearby. All I know of it was what the family called it, which was Twisted Chimneys - where my Dad was brought up by his grandparents.
