Let me demur, Archimedes, on the RN uniform. WSC did wear a creation, often seen in photographs, of his own design I believe, fundamentally an RN officer's reefer without insignia of rank. The cap, too, appears to have been a "reasonable facsimile" rather than pusser's issue. I do not recall ever seeing him shown as wearing an RN officer's cap badge. Maybe there is published authority one way or the other. I am pretty sure there must be, somewhere.
