The 18 inch cylinder steam whim (winder) engine house can be seen in the foreground with the 24 inch stamps engine house to the rear: the two square openings for the engine’s spring beams (to catch the engine bob in case of piston or pump rod breakage) can clearly be seen immediately below the top chamber window.
