Thomas 47 Insulator 2 Tier Brown Ceramic 10” Disks W/ Lead? HEAVY 24# Vintage.
This is VERY heavy. The top brown ceramic disk has a few chips. I can’t get it to pivot.
The top lead? Piece has the name Thomas, some letters “BTC” and the numbers 3S23.
I think the ceramic disks say Thomas 47.
Do not know the age.
