This shows the ware marks on the strange chunk of glass. No one knows for sure if it's a furniture leg or battery table leg? I doubt it's a sidewalk prism. Whatever this chunk of glass is... it's solid. Thanks again to my buddy Gil for the gift. Was bought at Rohde's Show in 2016. Wonder who sold it to him, and can they shed some more light about this whatsit? [id=519592340]
