A 6" 686 (a -2 if I remember correctly) with slots for Millet scope mount rings was up for sale at a gun show. I have seen N frames with those slots, but never a 686. Would that 686 be part of a special run? Or maybe they were cut by a gunsmith??
Except for the slots, it looked like a standard full lug 686. There was no box so I couldn't get a product code to go by. I should have taken a pic but didn't have the foresight to do so.

The ring mounts looked like these on this 629 (not mine..wish it were).


thanks for any help
