I’m not sure what joint this is but I’d like to get an lD shaft for this butt! If anyone knows what joint this is so I can continue my search, let me know!
Without pictures, this is going to be fruitless. Take your cue to the local pool hall or local cue repair shop and find out what you need. It would be helpful to know what brand the butt is as most makers use the same pins but not always.
