soco,I know that this thread has died a little but I might be able to help with Golden Hillock Rd.
between 1945 and 1968, I lived at 102 Golden Hillock Rd. 96 was a photography studio and 98 was a newsagents. 120 was a woman's clothes shop, I think it was called Draisies, spelling is wrong. At the end of that row of houses was a grocers store which was called Lancasters and the post office was next to that grocery store.
The woman's clothes shop, Draisey's, was managed by a Mrs O'Grady who lived in Cooksey Road, but the shop was owned by Mr Draisey who had a piece of land in Cooksey Road where he had a large metal clad hut to store his little Ford van which he used to visit small villages to the south of Birmingham, selling haberdashery. The site also housed several lock-up garages, some made from parts of Anderson air-raid shelters. At the end of that short row of shops, Lancasters and the post office, there was a general linen store at the corner of Golden Hillock Road and Byron Road.
