Well, if it's a 29-2, instead of a 629, then that's a whole 'nother smoke. If it's a 29-2, then there should be a pin thru the frame near where the barrel screws in, and the chambers should be counter-bored for the rims of the cases. This "P & R" status might make this revolver much more interesting to some S&W fans. If it's a factory nickel job, then the ejector star, the part that pushes out the empty cases when you depress the ejector rod, will be blued. The hammer and trigger should be color case-hardened. I happen not to care for nickel-plated guns, but it's a matter of taste, about which reasonable people might disagree. If this revolver passes Jim March's test, posted in this forum, and if it has the original box, tools, paperwork (unlikely), then I think Preacherman's assessment remains spot on.
