Boulton & Watt

Drawings for James Watt Junior's 102 ton steam yacht "Caledonia" are among the highlights of our paper Archive. Boulton & Watt's engines and boilers helped to power the nation. Designs for the Duke of Bridgewater are also included here although they were produced by Bateman and Sherratt Company: for a period they were producing 'pirated' engines using features patented by Boulton & Watt; who bought injunctions against them. The drawings are listed by the person or company the engines/boilers were designed/made for.
