Congrats on the find. I owned one for several years, and sincerely regret having to sell it off due to a change in finances. They are excellent revolvers, and tame down .357 Magnums considerably compared to J Frames.
Assuming the timing's good and the revolver is mechanically sound, you got a good deal too. Gotta warn you though, now that you've got a 2 1/2" version, you're going to want a 4" too. Trust me on this.
