For John Scott, draper, and Edward Jeffreys of Shrewsbury. Bog Mine, near Wentnor, Shropshire. This engine was similar to the first engine that Boulton & Watt erected in Cornwall, at Chacewater Mine, and some drawings were used for both engines. Originally all the drawings were kept in the same book, which the Drawing Office numbered 11 in their series of books of pre-1778 drawings, but in the 1890s Henry Hazleton separated three drawings and put them in a separate portfolio as drawings of Chacewater Mine.
