Penns Machine-Engine Factory at Greenwich [London]: the Erecting Shop, 1865. Engraving from a photograph by Mr. Nelson K. Cherrill, of ...the erecting-shop, which is that part of the factory where the engines are completely put together and erected, to test the perfect fitting of their parts before they are sent to the ship for which they are intended. The pieces of machinery which here appear in course of erection belong to the engines, of 100-horse power, designed for the Spanish iron-clad frigate Vittoria, which is being built by the Thames Iron Shipbuilding Company for the Spanish Government; but the two large pistons standing in the foreground belong to the engines, of 800-horse power, made for the new steam-yacht Mahrousse, or Bride of the Nile, one of the swiftest vessels yet afloat, which has just been built by Messrs. Samuda and Co. for the Pacha of Egypt. From "Illustrated London News", 1865.
