As you may see CP, i'm not into the everyday images that are in every book so seek out the unusual shots which are largely unseen which are sometimes LRO, sometimes out of print books and sometimes from private collectors who email me them. Glad you are liking them. The dock walls are certainly part of the other two buildings so I suspect so as it'd be a great waste not to have used what were already there, given as you say they were substantially built.
