Numbers can be the serial number, the caliber, the model number or the patent dates. Can you be a little more specific??
You will need to find a copy of the SCSW

S&w
You will have to contact S&W
Ruger and S&W come to mind.
The ammunition is called .357 Sig. Most pistols in .357 Sig can shoot the .40 S&W when you drop in a .40 S&W barrel.
Smith and Wesson (S&W) didn't make 38 special pistols in Spain. It's probably a Llama 38 special pistol, it looks a lot like an S&W. It was probably imported sometime in the 1960's.
Walther, S&W, Colt, H&R, IJ, to name a few.
The US Revolver Company name was used by Iver Johnson Company as one of their brand names from 1910 to 1933. The revolvers were made in .22 LR, 32 S&W, .32 S&W Long, and .38 S&W calibers.
If you call S&W, they will tell you when it left the factory for free.
You can download a manual for automatic pistols at the S&W web site or request one for free.
That depends on the value of "w", and on the value of "s".You can't simplify the expression, if that's what you mean.
