Sorry you have had no luck with the Model C, @Type79. They are quite rare and desirable. I have a couple of people interested, which is challenging to say the least.
Then why are you asking?
What are you asking?
You have interested parties? Sell it.
I am an "interested party" as a serious cue collector, and this sale isn't even on my radar.
There are only two people to ask about Palmer cues as far as I am concerned. Plastic rings or not. You got one of them here (@Type79), and I think his take is accurate.
The Palmer Model C cue is a slow seller. You seem to be experiencing that at the moment.
Why? Because it is not a Palmer cue in the classic sense with the classic style points. It is a "tribute cue". Yes, it is a legitimate Palmer. But more people want a Palmer with classic Palmer design characteristics because although he/they were an iconic maker, they were not necessarily great playing cues.
There are many Titlist conversions of that era which are worth more. I have a Ricco Gandy Titlist which I wouldn't trade for two or three of those. I have a 1966 Viking Titlist conversion I might trade even up, maybe. Maybe, but probably not as my cue is more rare and honestly probably a better player.
If you already know the game on this cue, why are you posting it asking? Just saying.
