Thanks for the help guys.
I ended up buying it yesterday for $400 friend to friend. It's a 681 no dash with a nice set of Altamont grips on it. The original magna service grips are also included, but the seller forgot to bring them. I'll get them from him in a couple of weeks. It does not have the M stamp on it so I assume it has not had the recall service done on it. The pistol was pretty dirty, but with some scrubbing and a little Flitz polish it cleaned up nicely. I don't think it's been fired much at all. I had thoughts about converting it to a 7-shot cylinder and having the barrel shortened to 3", but I think I'll just leave it original and shoot the crap out of it. The action is excellent, especial single action, which is amazing.
I'll get some pictures up when my camera's battery is recharged.
