Another borrowed item I haven’t played with it. It is very finicky. I hooked it up to my PM research mini power steam plant and I had to make a lot of adjustments to get it working, but it works. Makes nice sound and surely does pump water.
There is a video for you to enjoy.
Found through searching this is an Ernst Plank windmill pump from Germany. [ Guests cannot view attachments ]

That's a very interesting and colorful accessory!
