I don't usually get involved with these cue ID threads but that unique wght-blt got my attention.
Trust me on this, that bolt is not at all common by any stretch. GB cues doesn't use it. Almost nobody does.
Scroll about 1/2 way down the page to their replacement wght-blts. Notice the beveled shoulder.
You don't want to mix those up with what's being shown in this thread without risking potential damage to the cue.

I'm showing a pic of the one I have with a look at the socket I modified to remove the bolt from a Joss cue.
Measure the ID of the wght-blt recess and you'll know what to turn the OD of the socket to (3/8dr 9/16" 12pt).
I turned mine to .750" (-.002") and it works well. Unfortunately, I've only had to use it once or twice.
Diesel Mech. huh ? At one time I was an inspector for Detroit Diesel, back when they were 2-stroke and still
owned by GM. Kinda glad that I don't live in Detroit anymore. Anyway..........
Look at the thickness of the silver deco rings for comparison. The GB's are contemporary; thin (maybe .015").
In the pic that A/C is showing they are at least .030" and possibly more.
That cue is meant to look vintage or it is vintage. Regardless of who built the cue the pts are first-rate.
Another oddity. All GB cues are signed, by what the website states. There are similarities but maybe meant to be.
The biggest obstacle for me is the jnt.collar recess. I've seen it before and may even have a collar like that
in the shop that I at one time removed from a cue. Not a chance I'd remember the cue.
A/C mentioned the shaft inserts. They're not of current design.
There's nothing wrong with them and they're right for that cue.
One more little oddity with the bolt. On mine there is a small channel ground in the threads about 1/2" below the head.
You'll notice bound sawdust in the threads in that area, bound with a single drop of epoxy would be my guess.
Good thinking really. Now, does A/C's have that slot ?
Not a slam-dunk because mine could have been done at the 2nd install. But if it does, that's not coincidence.
Bottom-line, for me anyway, Danny Janes worked with many other cue manufacturers in helping to build their cues.
He may have actually made other companies cues for them. If not a Joss, there's a lot of Joss influence in that cue.
Again, that's all I've got.........and I mean it this time.
