[AC Man]

Well it might not be odd to those that collect old revolvers, but it is to me. S&W Safety Hammerless 32 cal 1st Model Top Break. Serial # 77911. S&W catalog says 1888-1902. For first model. any way of narrowing it down?

This might help. Can't narrow it down but the BATF recognizes ALL 1st Model Safety Hammerless' as Antique. The 2nd Model Safety Hammerless are classified as Antique until serial number 91,401.
