A few days ago I went to see this old Planetarium . Very interesting to see how it works.

Yes and it is still accurate. It has the planets known at that time. I took a picture of all the gears involved but it was a bit dark there and flashlight was reflected in the glass window.

Eise Eisinga left a bookwork about how to maintain the planetarium. After each 20 years they need to repaint the part that shows the year!

There are some videos of it, but they're not in English.
