Yes, need pictures! My first pistol was (and still is) a 39-2. Great gun. Got mine when I was about 13 (with Dad's blessing) so I'm a little sentimenal about them. True it is an aluminum framed, 8-shot, double action 9mm....the first produced by an American company. Nickle was an option and some versions where steel-framed. Those are worth a fortune now.
Personally, I think it's one of the nicest looking semi's ever. Must be the wood grips & S&W blue.
In the early 80's this model along with it hi-cap brother the Model 59 mutated into the 439 and 459 by adding a windage adjustable rear sight. From there they evolved into the metal S&W semis available now.
