Actually, I think it may have just been Armstrong Whitworth. I've just "driven" down the road on Google Maps and the building has a date plaque of 1915. This yard was:
Charles Mitchell Co, Low Walker: 1852 - 1882
Armstrong, Mitchell & Co Ltd, Low Walker: 1882 - 1897
Armstrong, Whitworth & Co Ltd, Low Walker: 1897 - 1928
