Unfortunately there is no cue maker nearby. The tenon is not demaged. A new ferrule with right dimension will fit on very well. As far as I can see there are no threads on the tenon, and a new ferrule could be glued on easily.
Am I missing something here?
Nobody selling official or non-official ferrules for z2's?
I found www.loontjensbilliards.com/predator-pool-ferrule-for-z-2-shaft
They haven't answered my question about the material of the ferrule yet.
Thanks, Jon Birger
