Hi James,
I had no luck at the library,but all is not lost.Your foundry was at Hall End,there was a book ,but it was reserved.BUT,there is a book on Hall End,kept in the basement at Smethwick Archives.They would be able to give you details if you rang them,also they would fetch it for you.If you get a photo,let me know,i would love to see it!If you want any more help,ask me.Glen
