Thanks for the manufacture year. I guess I was misinformed about the ship date. It has been my understanding that S&W did not document a S/N by build date but logged it into the records when it was shipped as part of an order leaving storage. Some S/N supposedly lay in storage for months or even years waiting to be logged and shipped. Seems a difference of opinion about documentation dating. This particular gun was sold new in 1987, I have the sales ticket, so by that, it sat somewhere for 6 years. I'm confused, I guess.
