I saw this yesterday during a random visit to a gun store a few hours from home. It's a nickeled New Service in .357. Since the gun serial is from 1920, and .357 wasn't done until mid/late 30s, this is clearly a rebarrel. Nickel, best I could tell, looks original, and as expected slightly richer on the barrel than on the frame. I can go back on my way home tomorrow if I decide to pick it up. What's the collector value of a rebarreled gun like this? What dollar value would you put on it?
