Here is an awesome piece, IMO. This is one of my Bulldogs in a panel variation. On the diameter dimensions I have two sets of numbers. One is the top dimensions and the other is the dimensions taken at the widest parts of the bowl. It a nice sized piece with an incredible blast. Hand cut Bakelite mouthpiece w/Delrin tennon, hand made solid sterling silver “Double Diamond” fitment. Thank you very much for looking.
