These two are nearly Identical except one exhibits incuse marking and the other is ink stamped. The trademark is a triangle inside a circle like used by Franklin Porcelain, but with an "X" below it. These are about 5 1/4" in diameter and about 5 1/4" tall with a 1 3/8" diameter smooth through hole. The pinhole extends beyond the main body by about 5/8". I have no knowledge of precisely how these might have been used. Just a few scuffs between the two, so virtually no damage. They weigh about 5 pounds each, and to be "economical" they would have to ship flat rate. I prefer not to ship them, but would be happy to bring them to Springfield next week for $5.00 each or $8.00 for the pair.
