In addition to the early Newcomen type engine and the Boulton & Watt beam engines, the science museum illustrates the later development of the beam engine with this pretty independent A-frame Woolf compound type of engine built 1838-40 (according to Watkins, 1838 according to Crowley). The slide valve cylinders are 8" x 20.5" and 14.875" x 30". It developed 25 horsepower at 47 rpm. It was installed second-hand in 1880 at the engineering work of Davies & Bailey at Hemel Hempstead where it worked for over 70 years before being preserved at its maker's works in Dartford. It subsequently was donated to the Science Museum.

It is a compact, self-contained design well-suited for smaller powers. The tank bed contains the condensing plant but is not well-appreciated in this view.

My compact camera has coped reasonably well with the conditions but the ISO-push makes the picture more grainy - my Canon EOS 30 copes much, much better up to ISO 1600 but was too big to lug on a fortnight's journey by train to the continent.
