I'm like KY Jon, I don't say anything that the seller would find insulting but I don't give them any encouragement either.

I've seen a lot of 'overly restored' guns - while I don't know what it looked like prior to all the work the owner/seller put into it, I suspect it might have been in pretty good original condition before the butchers when to work on it. Like Damascus said, I prefer to see a gun in its well-aged condition than one made to "look like new." But that's just me....
