I just love this solid walnut top as an object; such a beautiful shape! To make it spin, one would just need to wind a string around the wooden peg at top, inside of the copper handle, then hold the copper handle lightly while pulling the string to get it spinning. If this is too much effort, I'd just set it on a shelf or use it as a paperweight, picking it up occasionally, as it feels great in the hand.
4 1/2" tall x 2 3/4" in diameter. Overall good condition, with one small split in the walnut and some dryness to the wood on one side, documented in photos.
