I had one back then. Has the removable poker and has a chamber (catcher) on the bottom.
Funny how those proto pipes are the same price today as they were in the 70's.
Never owned one. When I was in college I was moving into a room in a fraternity house that had the words "The Bijou" carved into a piece of wood on the door there was a US Bong in the room on the headboard of a water bed I was hoping to claim. Weird pulley systems abound. There was a loft built above it I assume for the room mate. I dropped my bags and left to get groceries with my Dad. When I returned my bags were moved and I was told that suite of rooms had been condemned. Damn it. The next room did not come with a bong.
