You can not tell the model number with just the serial number.
You will have to provide the serial number and a detailed description of the weapon.
The Smith & Wesson 586 revolver with the serial number AJY4338 was manufactured in 1983. Smith & Wesson typically uses a letter prefix in their serial numbers to indicate the year of production, and the "AJY" prefix corresponds to that time period.
Look on the butt of the revolver.
