These are seriously rare lamps. I only know of two with collectors but I had the oportunity to borrow this one from its owner John Kidger to photograph a few years back. Made by Gold Bros P. L. Ltd, Lower Tower Street, Birmingham, England in the mid 1920s. It has the look of a BP Cleary about it but is different. the patent stamped on the lamp was applied for by Arthur Ernest Harbord of "Holly Mount" Old Warwick Road Olton Warwickshire on Dec 7 1922 and was granted Dec 20 1923. This lamp therefore was made in or after 1923.
