Riisager wind turbines appeared in many diferent confi-
gurations and sizes.
It is unknown to history, whether those uninvited guests were
able to make use of whatever they found during their nightly
espionage raid in Thy. But as I am now in possession of the wind
turbine in question, it can be revealed that in the nacelle made of
plywood there was a second-hand heavy-duty rear-shaft from a
British military vehicle integrating main shaft, brake and gearbox.
