The value of pipe #234 is n/a points.
Hooray! The Venturi collection is now complete. C. E. Davis offered this white pot on eBay and I was the lucky winner. Not only did I get the white pot, there was also a black bent Venturi that went straight-away to the Pipes for Sale page.
It took almost three years to get an unsmoked example of this shape/color, but at last I can offer this one to someone else. Norm Jones got it to help fill in his collection of Venturi pipes,
