That's a very nice revolver, I'd be happy to own & love it. I would submit that it's a full production gun and "early 90s" puts it -well- in to production by ~10 years. It's not rare, it's not specifically collectible.I have a 6" that's basically new, early 90's vintage. I doubt it's seen 20 shots. I have no intention of selling it though.
You left out the 8-3/8" barrel...
