I picked this Model 66 up last month.
It was in the case at a LGS. It was marked about $100 cheaper than the M-19s next to it, probably because Cletus had, in the past, polished it. And, to be honest, he didn't do that good of a job. But it had S&W target stocks (which I hate) and the lockup felt really nice, almost newish.
They had two. I called a buddy, who drove over and rescued the other one.
