Maybe the Dr. Graybow historians can give me some information on the little cutie. The shank is metal ang goes through the bowl, there's a cutout in the tubing to allow smoke to travel up the shank, the fishtail stem is removable and the bowl is large enough to take one flake of PS Luxury Twist Flake which is what I'm smoking in it now. Although it is probably classified a Bulldog I'd be inclined to call it a Pug, I think the flake of tobacco weighs about the same as the pipe!
