The 686-4 is part of Smith & Wesson’s stainless L-frame line and, in this configuration, features a 6-inch barrel with a full underlug for added muzzle weight and a serrated top rib. The satin stainless finish is applied across the frame, cylinder, and barrel.

Factory markings include the S&W monogram crest on the right sideplate and the “MADE IN U.S.A. MARCAS REGISTRADAS SMITH & WESSON SPRINGFIELD, MASS.” legend on the frame. “Model 686-4” is marked on the yoke cut. Matching serials were observed on the yoke cut and the butt (number not disclosed).
The sighting arrangement is a pinned ramp front and an adjustable rear; on this example, sight components are incomplete, and the front sight’s insert is not present. The gun is sold as a stripped Gunsmith Special frame/barrel/cylinder assembly suitable for parts or a project.
