For a $30.00 fee you can order an historical letter from S&W. Their in-house historian, Roy G. Jinks, will research the original records until he finds your gun, and then send you whatever detalis they have recorded. This usually includes the background history, the revolver's original caliber, barrel length, finish, and to what distributor or dealer it was shipped to along with the date.
