Hello everyone! I bought a box of very dirty Lego for a few euros, mainly because I was interested in the 8720 Technic engine (which is waste due to leaking batteries...). At home I noticed that the blue tower is glued and has “Lego Systems” written on the base. It seems to be some kind of electric windmill for a shop window. There are a few more sets that go with it, some of which I was able to research on Bricklink, and which are also glued. A train with trailers (720-2), a vintage car (part of 348-2) and a living room (260-3). The Windmill Set (318-1) is also included, but not glued.
I think it is a display set from the early 1970s. Does anyone know this set or have any other information for me?
Here are some pictures:

I am thankful for any ideas.
