I have never seen anything like this.
Hand forged cast iron.
Old horse/farm bits.
Antique mid-late 1800's horse hames, heavy cast metal with brass balls & cast iron hardware.
These were worn to pull carriages.
The top is a heavy metal tray that sits on it, you can use it or add your own as it is not attached.
All handmade (a LONG time ago).
Stands 27.5" tall and 18" wide.
Top is 13.5" in diameter.
Excellent condition, in last pic you can see it is missing one small piece where the top sits, this does not affect it in anyway.
