This is an unusual set up. The bowl is first screwed through to a metal "holder" and then screws into the stem. There is a card washer to assist in a smoke seal.
The pipe is 5 1/4 inches (133.5 mm) long and from underside to top of bowl is 1 5/8 (42 mm) inches
These images are from Doug Bisbee, who, unlike me, has managed to acquire an example
Doug says the attachment that is on the bottom of the bowl has threads on it and it threads onto the pipe it is not a push-in fit and the hole does not line up with the draw I really don't know why it's even there that's why I said it could be considered a screw through or a screw on because it really is both |
