This is a nice puzzle. It is a barometer in the form of a monument to the SMS Iltis, the German naval ship that was shipwrecked off the coast of Shandong in 1896. But the real puzzle is its relationship to the memorial unveiled on the Bund at Shanghai in 1898. They share the broken mast, and the tangled ropes, but it is not a close copy, and the broken mast was a common funerary symbol. I have not seen its like before, and would be interested to know if anybody else has.
