I was told by 2 Heisey experts that this is a #394 Narrow Rib Dr. Johnson's punch bowl and that it was designed to serve Dr. Johnson's punch which is served hot and that is why it is so thick and heavy.There is a notch cut into the rim to accommodate the ladle and this must have been done by a professional. It is marked with the "diamond H" as pictured. It stands 10 7/8 inches tall, 10 7/8 inches in diameter at the top, and 6 inches in diameter at the base. I will include a copy of Dr. This beautiful piece is in excellent condition. The item "Heisey #394 Doctor Johnson's Punch Bowl" is in sale since Sunday, August 5, 2018.
