Ball Spire Finial

I tend to think of a finial as a decorative item atop something...but this (an' its near-double in the link below) seems to be intended to hang. As the link is for a clock part, I can perhaps see it as a weight to move an escapement...but the hole at the end isn't threaded, an' the wee hole on the side beneath that one is a puzzle.
It is ~3 3/4" long, ~1 5/8" major diameter; it weighs ~7 ounces. Are any of y'all into old clocks? Does anyone recognize this thing, especially if otherwise? How 'bout an age estimate? Thanks for lookin'!

To be attached with an allen bolt?

 

Not a doorknob, of course...the end hole on mine is 0.113"; the side hole (also without threads) is ~0.057".

 

No, of course not, I just added that pic as it was the first one I found that showed an allen bolt being used

 

I found that link as well. I found this one on eBay https://www.ebay.com.my/itm/304332033447
or could it have been a clock finial with the hole mounting/joining a gallery to the other finial?
