I'm considering getting into collecting and shooting these old wheelguns and since I have very little experience in revolvers any tidbits of information or what to look for would be appreciated. I've already did some research on M&P's, Victory models, and early N frames, along with New Service and Police Positive Colts. Anything in particular worth looking for during the interwar or postwar period up to 1957 from these makers would also be appreciated. I plan on starting slow with the basic, more common models and go up from there. I'm more interested in the history of these collectible guns then their investment value. Or to put it another way, I don't have large amounts of disposable income.
