I once had a crystal leisure cue made by Joss that didn't say Joss on it. I sold it to a buddy who still plays with it. Years ago when I was investing it Joss had a website "Joss archives" and there were brochures for a couple different companies like Chrystal leisure that didn't have the Joss name on them.
I remember the archives well. They had models for various distributors. I have two of those, both say Joss on them, not on the butt cap, they are stamped Joss on the joint collar with a Joss number.
I'm not doubting what you say. It's just that I keep running into what Dan said and some confusion about who made certain lines of cues. I don't know how to resolve it.
There are cue lines that were made by Joss that were not marked Joss as far as I know, and as you observed. But those same lines at different times were made by others. A good example is Brunswick. Traditionally, we often say the 14 pin cues are the Joss ones, but I don't know if that is really consistently valid because Falcon and others used 14 pins.
Examples:
Brunswick
Biagio
Longoni
Those cues I mention do usually say Joss, often in very tiny letters...but I have seen that they don't always say Joss.
From 1996 through 2022, they should have a serial number. But do they all? Of course the cues we are talking about here are from a 1996 catalog, so that does not apply.
These particular Corvette cues are from before the huge influx of Chinese clones and fakes, so that's not what I am talking about.
Finally, I have an observation and a question. These are overlay cues. Joss made overlay cues?
