I wish they'd include info on caliber and bore condition. But then few auction sites do; they seem to all treat "kentuckys" as objet's d'art.
I suppose that's because that about all they are now days.
Not many guys, if any, take these guns out and shoot them any longer. I know when I buy a gun my primary concern is what the exterior of the gun looks like. I like to look at several interior things as well; The patchbox cavity, the lock interior works and lock mortise inlet, and I also look at the muzzle to see the bore size and if it's rifled or smooth. These 'looks' are more to determine originality of the parts to the gun, and not functionality. Like if you find a sub 40 cal bore on an 1800ish PA rifle, you better take a closer look at the gun.
Once I have the gun home, I enjoy examining the bore to see the different types and styles of rifling, etc, and usually give it a good cleaning, just because.
A nice bore on a rifle is nice to see, however, shootability of the gun has never been a concern to me.
I suppose others look at it differently, but to each his own.
