Daniel,
actually, that picture is of the *second class* purser's office on Olympic, which would give a similar representation of the purser's office in first class and on Titanic.
One could make some sort of a guess as to what the office face would have looked like, based on woodwork on the grand staircase. Also, I would think there'd be an illuminated sign suspended from the ceiling indicating the purser's office. Detailed general arrangement plans might help, and I do know there's a detailed GA Olympic plan from the 1920s one could get a basic idea from. One thing, however, those plans are after two extensive refits. The purser's / inquiry office arrangement might or might not have been changed, and there's no telling if Titanic's and Olympic's were ever originally identical anyway.
I've seen good, detailed GA plans of Titanic, but only for first class and exteriors. Bummer.
