Hi BordesleyExile.
My father worked in the office of a company called Hoskins & Son in Bordesley, right alongside the railway. They manufactured hospital beds among other things and some of the components were manufactured from cast iron. They did not have a large foundry but I well remember being taken to the factory as a child (I'm talking early 50's) at weekends and watching the chaps re-lining the unit with new fire-bricks.
If anyone remembers the company and has any information on it I would be most grateful.
