Another 20-2 accounted for, that's great! I've added another picture in my post of the left frame under the grip for anyone who may care about the markings, which are almost exactly like Ed's gun.
Austin P.D. #208 (one number up from Ed's #207) was also accounted for by S&W Forum member Savoy6 back in February of this year (2007).
Here's a link to his thread on his 20-2. It would be great if he were still around to chime in on this thread and maybe add some pics!
