hard to find...
I don;t really think that Meucci make or made bd's for other than their cues.
I am not sure but I think was someone else here also who's looking for a bd...3/8x10, maybe?
You can buy one and change the thread...but...will cost you more than the shaft itself.
If you find one shoot me a pm. I am interested too.
Sorry for the bad news,
Chris
