The stocks represent a style used from about 1920 to around 1929. In 1920 they reached serial numbers in the 346,000 range. By 1932 they were up in the 628,000 range or higher. so early 1920's would be a good estimate on your gun. But none of this is cast in stone. The only way to know for sure is to order a historical letter from Smith & Wesson. This is the procedure"
You will need a snapshot of the gun, a full description including the serial number on the butt, and a check in the amount of $30.00 made out to Smith & Wesson. In exchange the company's historian, Roy G. Jinks, will research the original records (which are not computerized by the way) and send you a letter containing the details of what he finds.
This comprehensive document will contain an overview of the model’s history, followed by the details of your particular gun. This usually includes the caliber, barrel length, finish, and the exact date it was shipped from the factory, and to what distributor or dealer. If there are any special features they will be listed too. This information is often invaluable, and should you sell the gun sometime in the future you can easily recover the cost of the letter.
