I have a couple of old Grabow Golden Dukes that have a Lee type hidden, recessed screw tenon and mortise joint.

Except for the Grabow accepting Medico type 6mm filters it works the same as a Lee Star Grade.

The Lee system debuted in 1946, and the Kaywoodie type about 17 years earlier. The Kaywoodie has a one piece stinger tenon difficult to adjust, and a mortise with an aluminum disc visible to the user.

The best I can date the Grabows is the 1950s or 1960s. They came varnished. Some of the Golden Duke pipes had spectacular grain. This has the 1956 patent Adjustomatic stem.

I think any of these are superior to a push stem. Push stems break the tenon or crack the shank, or get loose or too tight or get stuck on occasion. A push stem needs cooled to remove the stem.
A screw stem lasts the life of the pipe, and gives no trouble.
It must cost more, especially the Adjustomatic, to make a screw stem pipe or more makers would use the system.
