Dean,

Quite an interesting item you've found there, never seen anything like it before.

The only thing I can think of is that it may be some type of clip to attach and hold a small flag or standard on a round wooden or metal rod for some kind of a Stammtisch assembly..? That might explain the three curled devices at the bottom edge, where the rod might slide through ... hmm? ... tough call indeed.

The thing that's easy enough to distinguish is the great eagle and crown artwork. This has to be the best Art Deco design of the royal crest I've ever seen, very futuristic when compared to the normally seen renderings. Being able to see the eagle's talons through the modernized Hohenzollern crown is a splendid touch.

I really look forward to hearing more ideas about what purpose this piece actually served and hope our members will take time to comment.

Thanks for letting us check this out.

Best!

Bill
