Dorman Long & Co. Ltd. - Technical Drawings/Plans

Drawings of products manufactured by Dorman Long at their various works. The majority are bridges constructed at the Bridgeyard at Britannia Works, but others are from elsewhere. Many of the drawings contain information identifying other companies as being the originator of the drawings, this is because it was standard practice to sub-contract parts of the work due to the size or complex nature of the structures being built. The drawings have been catalogued where possible by product and then by individual contract.
