u/No-Quality-369

Found in a riverbed downstream from an old Smelt Mill. I've been there a few times, found lots of crinoid fossils and baryte but never found another piece of this

I can't seem to find any instructions online. I feel the retractable part unscrews where the two knurled rings are.

(survival mode) First picture is maybe my first choice, a Gondolin from the Silmarillion by Tolkien kind of castle. Although I would want to lower the height of the land buly quite a lot and it would take ages. Also the snow fall would be annoying. Second pic looks good but maybe not that much space? Fourth pic, would be good to be near the sea so I can include a port and ships.
