I have a couple of S&W revolvers (15-2 & 17 ) that have more holster wear than I like to see, so I was wondering if the value of there would be dimished to the point that it would not be wise to send them to Blue Ridge to be re-blued. They will be enconcsed in a collection and fired very little if at all. I know that re-finishing a Colt, detracts from the value, even if done by the factory. I just don't get the warm fuzzies about current S&W detail workmanship.
