I just saw a Titanic model at the "Titanic Science" exhibit in Richmond, VA. It had a small set of stairs on the hull on the starboard side of the ship under the wing bridge at about E deck level. It looks like these might have been removable stairs for boarding purposes--perhaps to let the pilot on board? I've never seen them depicted on any other model or drawing of Titanic. Can anyone shed any light on what they were?
