A close-up of the port aft poppet under the Royal Navy battleship Albion (1898) in the Thames Iron Works shipyard at Blackwall, London. The photographer is looking aft from the port side of the slip showing a man in a bowler hat in the foreground looking at the camera. The port propeller is fitted but only two blades have been attached. Tugs dressed overall are standing by in the background with the yard's sheerlegs beyond them. A vertical format negative. A note on the negative says the photographer is using the Camera B.
