I would like to determine the date of my S&W top break .38S&W 5 shot revolver with a 5" barrel. It has the grip safety and the last patent date is June 5 1890. It has S&W black plastic looking grips, the s/n on the butt is 1461xx.
The presence of the grip safety makes your gun a Safety Hammerless model (Lemonsqueezer). The serial number would make it a Fourth Model, manufactured from 1898-1907.
