All the numbers you mentioned are just assembly numbers that were used in the production of the gun, and have no significance now. The round stickers are inspector's stickers. The serial number can be found on the butt of the gun.
The .32 magnum model 631, 631 Lady Smith, and 632 Airweight Centennial were produced in very limited quantities for a short time in the early 90's. As such, they are fairly scarce and usually command a high price. A 631 in like new condition with original box, papers, and grips recently sold on Gunbroker for over $1000. Your gun would have shipped from the factory with Goncalo Alves combat grips like the ones on the middle gun in the picture. Even without the original grips or accessories, you probably still have a $500-600 gun. You got a great deal on a really fine revolver!
A lot of folks, me included , really like the J frame .32 magnums. They offer the advantage of 6 shots vs. 5 when compared to the other J frames, plus you have the option of firing mild .32 S&W long ammo for practice purposes.
There was another very recent thread on this same model that will provide more information if you will do a search.
