Totally agree, if the revolver is not marked or signed somewhere as to who did the work, often times you can narrow it down by making a note of the features as most of the builders found one particular way they liked to do some part -- and then they did it the same same same each time.I have never seen that trigger guard mod before.
Its quite interesting, could be a clue as to who did the work.
Also check under the grip, could be markings or other clues.
Exactly my sentiments... the old school PPC competition is all but gone so the demand for these is excruciatingly low, but if you just want one to shoot and enjoy, the value is unbelievably high.
I am no manner of an expert, but I would believe that nearly any/all PPC revolvers of exactly this style is spec'd for the Federal primer and will give many, many misfires, especially in double action, with any other primer. I own three of these revolvers myself, and that is the case with all three.
I have also experimented (with all three!) in adding more mainspring tension and getting a harder primer hit -- I have succeeded with each, however it absolutely affects the totally inspiring double-action trigger stroke, so I ultimately put each of them back as the builder had set them.
It's been said many times, I'm sure some folks don't care to hear it, but it's no less true regardless of opinions. When you really want to try and get an idea of what a particular gun may be worth to sell, the best indicator is to go to the largest market where most of that particular item is sold, most often.
I don't know of any single place where you are more likely to find an older, used, and worn PPC revolver, especially one that is a K-frame S&W that was customized in the 70's or 80's... than Gunbroker.
And I can tell you confidently, experience has shown me that the revolver in post #1 is worth more than "$200 - $250 as a paper or tin can plinker" and that a Bill Davis in any condition other than broken/non-functional is going to sell for more than $400.
rubiranch, please feel free to send me a PM if you're interested in selling that to me, but my suggestion is to put it up on Gunbroker with a lot of pictures.
Here you go
