Thank you for the responses, Gentleman.
My name is Jack Müller, and I am an American of Scot (clan Agnew) & German extraction. I fancy myself as a perpetual political & military Science student, because learning is never concluded. I view Cardinal Richelieu the cleverest of history's diplomats, Henry V my personal hero, and a toss up between Cromwell and Pitt the elder, as the best thing that ever happened to the Mother Country. I am quite ancient, and have been scratch building since childhood, and I build exclusively in traditional 1/32 scale.
In answer to the Crane inquiry: Yes, this is one of 17 cranes employed at the port of Zeebrügge during the Great War. All were electrically powered excepting a 10 ton steam crane on the mainland. My example is one of six 2.5 ton cranes in service there. Four of these cranes served on the Mole and were modified when the Germans added the extended boom under the jib. This was to provide additional clearance over the edge of the quay for lowering and retrieving aircraft from the inner mole.
I might add, I am surprised no one has commented on the rail car beneath the crane.
