J&J Cues wouldn't be able to help you with regards to learning more details about the cue, you'll need to contact TAD Custom Cues directly with the serial number (Phone: 714-995-1644). As for this cue, the bumper screw shouldn't be an allen screw. Allen screws are fine threaded and go often into a weight bolt, which this cue shouldn't have one. The bumper screw for this cue should be a very small phillips wood screw, very easy to strip.
With how the thread was earlier, I don't know if he's messing with you or trying to be sincere...
Attached picture taken from one of Timothy Song's posts to show as an example of the bumper screw.
mamono - Thank you sir, very pertinent info. "very small phillips wood screw, very easy to strip". This is precisely why I did not want to fool around with trying to remove the bumper and was hoping someone here could give me at least the range of years this model was made. Oh well, such is life. You have no idea how much I appreciate this info and ESPECIALLY the photo. Thanks again.
p.s. Regarding the "It's a Joss." I've no idea if he was serious or not either but, actually, the entertainment value of his comment came in at 3 1/2 stars! :grin: AND THANKS FOR TAD'S PHONE # !!!
