Miniature whatsit ?

[Grundestoun]

I bought a bunch of brass miniatures at a thrift store. I have identified every one but this one? I have no idea what to call it to look it up. Did a search of brass miniatures and did not find one like it. Any help appreciated. Thanks!!!!

I see some listed as decorative or ornamental (rather than functioning) gyroscopes.

Yes have the same one. I think these are made in Germany.
