I, too, think that Neil is absolutely right as far as the port side is concerned; however, when I look at the three photos to which Colin linked above, for my part I cannot see anything that looks like a corresponding structure on the starboard quarter of the wheelhouse, and would thus be inclined to think that there is only one such external access door, not two … or am I missing summat too obvious for me to spot?!
