I have a 98% Model 15 Combat Masterpiece SNUB. I believe it was unfired or very close to unfired when I traded for it. I put 50 rounds through it in a snub match a while back. It had a turn line already from being handled, so I doubt I hurt the value any at all. I plan to sell this one myself, and get another toy to play with, like an SP101 Snub 22LR. OR a Steel J Snub in 22LR
I have one kid who will keep what he gets, and one who will sell them. I probably should make a list of who get which ones myself. Make sure the one who will keep them gets the good stuff.
Your Stainless Steel rear sight 66 would qualify for the Good Stuff List.
