I think you will have fun with it. Don
According to the book, your gun was made in '68 which would make it a 17-3. Open your cylinder, and look in the cutout on the frame. It should say 17-3 above the serial number.
I have a 17-3, and it is accurate!!!
The turn, line doesn't necessarily mean that it has been fired a lot. It could be that someone just cocked and let dowm the trigger a lot to help break in the action. I do that all the time with my centerfires, and dry fire them at people I don't like on TV.
I never dry fire my 17, because it's a rimfire, and S&W doesn't recommend it for them according to their web site. I know a lot of guys will tell you that it's OK with Smith's, but I won't be one of them. You risk damaging the firing pin, and the rear face of the cylinder.
They're not making the original 17's any more, and I would much prefer one over any conversion kit for your 1911. I have shot guns so equipped, and was not impressed. My 17 will shoot any of them under the table.
Most every single 17 I have ever handled had some side play (rotational), so I wouldn't worry too much unless it is excessive.
