The International Exhibition: Messrs. Maudslay's engines of 800-horse power for the Valiant, 1862. Motive power for steamships. 'The largest marine engines exhibited were those by Messrs. Maudslay, intended for the Valiant; they are of 800-horse power nominally, but capable of being worked up to a much larger amount. Portions of engines 1850-horse power were exhibited by both Maudslay and Penn. The crank-shaft exhibited by the latter was a splendid piece of wrought iron, beautifully finished. In the eastern annexe was a crank-shaft of similar dimensions, made at the Mersey Ironworks, left exactly in the state it came from the hammer. It weighs about 23 tons'. From "Illustrated London News", 1862.
