You are considering a vintage Smith & Wesson Adjustable Rear Sight Assembly. This sight is truly a rare sight… to see. Old-Model Smith revolvers utilize the squared-off rear sight leaf design, which came in a non-standard variety of lengths and tang screw-hole locations; after 1992, Smith & Wesson standardized their rear micrometer sights, switching to a rounded edge and shorter 1.60″ length. This example is an intergenerational hybrid variation, featuring a round end but a longer 1.86″ length. This variation was typically found on Model 29, 629, and 625. It measures 2.400″ from slide holder and 1.865″ to center hole. The condition is Excellent, showing minimal wear. It does not come with the elevation stud or leaf screw.
When ordering, please pay close attention to two measurements of your particular firearm; the first is from the center tang screw hole to the edge of the blade holder (Please see photo for reference); the second measurement is the overall length starting from the same edge of the blade holder.
