The right side of the barrel only tells you the caliber the gun is chambered in, not much about the model or the age of the gun. There may be a letter like "S", "V", "C" or "K" on the bottom of the grip before the s/n, the gun may have round or square grips, 2", 4", 5" barrel, etc...
You will need to provide some additional information, AND some pictures of the revolver to get a meaningful answer, and even then the condition of the gun may be hard to tell from pics.
