I find it very interesting that Janes used such a thick joint collar and the metal rings like the Adam.
Metal rings in a JOSS? Wow.
As I mentioned on the first page, Dan Janes would be a possibility, given all the pictures. The Bushka rings make it rare for Joss-made.
A thick joint collar? I think you mean the stainless steel joint. I'm not surprised it's thick. This is a birdseye cue, and the buyer obviously wanted a very heavy cue, 21 ounces.
Joss, in the mid to late 70s, made mostly ebony pointed and butt sleeved cues, which helped achieve the desired weight.
This cue is nothing but maple, and the weight is obviously heavy by the sticker. Somebody wanted a very heavy maple cue, 21 ounces.
There are three places to manage weight on a cue. The joint, the A-joint, and the butt sleeve weight bolt, if needed. Wrap wood could be adjusted, but was maple in those days. This is a few decades ago.
The joint could be made thicker to make the weight higher, and keep the balance about right, a couple inches above the wrap. Nothing about this really surprises me. I suspect Dan Janes used a thicker stainless steel joint to make the weight what the customer wanted. Who knows whether the customer was Jim Rempe, or a customer of Jim's...
All the best,
