Radiators on Shipley-made Scotts were made by the Northern Radiator Company Ltd., of Sheepscar Street in Leeds, and their ID plates are on the underside of original radiators. I do not know where Brum radiators were made in later years.

Thankyou for your replies gentleman. I have just had my Brum radiator re-cored and was contemplating putting the tag back on and the significance of it. Kevin.
