The hull of the Royal Navy battleship Cornwallis (1901) under construction on the building berth at the Thames Iron Works shipyard at Blackwall, London. The photographer is standing in line with the keel blocks at the bottom end on the berth looking up the ways. The bottom frames from 151 forward are in position and frames 139 to 151 show the cut outs for the port and starboard propeller shafts. A note on the vertical format negative says the photographer is using Camera B.
