Less than 100 to over 1000 depending on specifics.
brand new it would be worth 750$.
Smith and Wesson 9mm Model 39-2 Chrome finish.
Actually, that is nickelplating, not chrome. These were commonly made by Colt, Smith & Wesson, Harrington & Richardson, Iver Johnson- and just about any company that made a .32 revolver. There have probably been more than 100 makers of these revolvers.
I have a friend who has a 32 cal, break open hammerless revolver, chrome finished, in excellent shape. As near as the person who had it remembered, it was perchased around the early thirties. It is stamped American Revolver co. with ivory grips.
