Weird Bronze/Iron Thing

[nkellam22]

I found this item in Luxembourg (Western Europe) in an area with stuff from the 1600s-modern times.
The top part of bronze or some sort of copper alloy with the bottom part being iron and is very heavy for its size.
I have no clue as to what it might be so any help is much appreciated.




Thanks!

A bell clapper maybe?
