To determine the year of manufacture for a Smith & Wesson revolver with a serial number of 188456, additional context is needed, such as the model of the firearm. Generally, Smith & Wesson provides serial number ranges that correspond to specific production years. For example, many revolvers in the 188,000 range were produced in the early 1900s, but for an accurate date, it's best to consult a detailed serial number reference specific to the model in question.
