I am not sure if Joey will chime in this thread but he is the source for those ferrules.
Last time I heard from him he stated the ferrules might come back through another source but I am not sure if that applies today or if he has given up the idea of bringing back those ferrules, they are my favorite...
That's news to me. I never said it might come back through another source.
Some people might still have a few laying around.
Good luck in finding a few pieces.
I could be wrong but what I heard is that you might have a pool cue supplier manufacture those ferrules. If I am incorrect my apologies, I misunderstood.
