Well I went ahead and picked it up the Model 17 I had on lay-away. It's got a little more blue wear than I noticed the first time I looked at it, and I didn't see that little piece of the grip that's broken off, but they don't really matter. I'll probably replace the grips anyway.
I was told by a fellow on "The High Road" that it was made in 1971.
I took it "down the hill" when I got home and ran a dozen or so rounds through it. It rolled a can around just fine.
