Can someone give me a bit of help on a gun? I'm looking at what appears to be a S&W .32 double action, however, I'm not sure of the model. It's blued, with the semi circular front sight. The serial number is 25,795 which would make it a "third" model. I think I can get it for about $140. I'm not real good a judging condition of such an old gun, but a knowledgable friend who was with me estimated the condition to be about 80% for a gun of this vintage. Is this a keeper or something you'd pass on?
