After many years away from smoking pipe. I have brought out my Jobey 300 it was my very first pipe. I would like to replace the threaded insert that goes into the shank of the bowl. Which the stem fits onto it. I believe Jobey may have been unique in doing this. I bought this pipe in the late 70s or early 80s not sure of its date. Anyhow, where can one get these threaded inserts for Jobey pipes nowadays? Not seeing anyone selling Jobey online I am guessing they are no longer in business. Appreciate any advice or help to point me in the right direction.
