I've heard about them but never seen. Do you mind cleaning it from dust inside and oiling the mechanism?

Well, it’s a sophisticated question… I did photos 6 years ago for the original post. The gadget is a part of decorations in my apartments. I have a task in a trello for reparing & cleaning the gadget… however, I have moved it from Chelyabinsk to Saint Petersburg only.

I think it would be a good idea to use soft type of anti-rust chemicals. I'd recommend a Trilon-B. It won't do any harm to the metal as it's not an acid.
«Right shit» by 1 — please read your post carefully. However, a very nice antique mechanic piece of equipment :)
