I have an opportunity to buy a 32 Top Break Double action, 4th model, blued, S/N 224181, and would like to tap into some of the knowledge here. I haven't seen it in person yet, but have a few questions. If it's the original finish (sort of doubtful), are blued ones preferred over nickle? I'm aware of the hammer push-off issue, and, assuming the revolver is in good shape, is $250 a decent price with the ammunition? I'm familiar with more modern S&W revolvers, but this would be my first antique, and I'm sort of intrigued. Any insight would be appreciated.
