I know this isn't a particularly Smith and Wesson related item but there are no doubt board members who also like good lever guns.
Time to start thinning out the stock of assorted parts laying around. This is the Marbles Peep Tang Sight (#009832), adjustable for both windage and elevation.
Comes with 3 different screw-in sighting disks. I know for sure that it will fit the Uberti '73 but probably also fits a slew of others. This sight is in excellent condition.
