Smith Wesson Age By Serial Number

I've been drooling (figuratively ) over a 'Dirty Harry' Smith & Wesson 6 1/2' model 29-2 w/ PB, TT, TH, & RC serial numbered N63xxx at a nearby shop, and am curious re its date of manufacture. All sorts of references -- oldguns.net being my favorite -- for dates on all sorts of firearms, but I cannot seem to find any site/source for this Smith & Wesson firearms!
Might you direct me to a source -- other than sending $75.00 to S&W -- where I might look up/ascertain its age? (Or, better yet if you know, and will provide info to me!)
Thanks much!!!
