Beautiful TW. Which revision is it? Hard to say from the pictures. -1? -2? And if you don't mind how much did you pay? Mine is a -1. While some people are posting over-inflated prices on the auction sites, I think the $650 range is about right.
The only thing I'd like on mine is to chamfer the chambers and make the front site replaceable. I might have to give in and get a Pro-Shop SSR model. Probably cheaper than machining my older one. They're selling NIB for about $770 on-line
Don't know the revision, when the cylinder is open the numbers AHI1988 and under says MOD 686 are on the frame.
than on the yoke it has A10 and under is a 32349 number. There is a V on the back of the open cylinder. It also has the MARCAS REGISTRADAS under the Made In The USA engraving.
If that helps I'd love to know the revision, and what differences the -1 and -2 mean.
I think the dealer said it was 1988. But I stole it for under $500.

Thanks alf, I know your an aficionado on S&W Revolvers.
