Vintage cast iron molding tools made by Acme for Chattanooga Roofing & FDY Co Chattanooga Tenn. 4 pc are 11 by 3 inches. The odd piece with the embossed writing is 8 by 7 by 6 inches all very heavy and seems to be in very good condition.

All that said I have no idea for what it was used for. If you know please let me know.
