METAL OUTER BOWL
The Curtis Custom-Built Pipe Model 100
Manufactured by Curtis Industries of 1120 East 222nd Street, Cleveland 17, Ohio. First seen around 1946
The actually markings are “Design by Curtis PAT .PEND. “.
The bowl insert appears to be briar, despite having only had many examples am still unable to get the bowl apart, I am loathe to risk damage. The top plate does revolve but whether it is a screw attachment or a push fit cannot yet be ascertained
The interior of the stem is more complicated, taking an inline filter inside the tube. The shape of the end plug makes it more than interesting to undo. On many examples this part is the piece most damaged by pliers
With so many threads in the ‘gunk’ part of the pipe it can be a problem to clean.
