Revolver gurus, is there a way to tell if Bill Davis worked on a non-PPC revolver? Just bought a Model 66-1 that belonged to my boss. It was his duty gun back in the day, and he bought it from another LEO who supposedly had Bill Davis (or at least his shop), tune up the action a little. It definitely has a nice trigger, but otherwise is pretty much a normal 66 from what I can tell. Just curious if there was a way to confirm Bill Davis actually worked on the gun.
