Hamm’s Old School Dry Pipe

Hamms waterworks hourglass recycler. Basically his inside out tube with a restriction in the middle. Super fun function and really pleasant to rip. Had some sand blasting accenting that is pictured. 14mm joint, signed, numbered, and dated (11/21 #28). Minor water makes (super minor) and no other flaws. Has the larger diameter mouthpiece which I think is superior to the other style. Comes with tube only.
