I ran across a blue 29-3 in 8 & 3/8" a few years ago at a good price and got it. Hadn't had a box through it, as far as I could tell, and had the original papers, registration card, screwdriver and swab. I use 44 spl level reloads in it and it is superbly accurate. It may be the nicest-looking revolver I own. gets taken to the range now and then, it's too long to carry anywhere else. It's one of those guns you don't really "need", but you wouldn't want to part with, either...
Mine came with the ratty cardboard box, I like your wood presentation box much better.
do let us know how is shoots. I'll be surprised if you can't get 1 & 1/2" groups at 25 yds.
