I have a stainless 357 magnum, with 8 3/8 inch barrel, pinned barrel, 3 screw, adjustable rear sight, s.n. N695xxx on butt and on yoke (?) and MOD. 27-2 under the sn. I am wanting to know the date of manufacture. If anybody can steer me to a ser. num. chart, I would appreciate it. This gun is like new, with a wide trigger and wide hammer, both checked. Grips are Pachmayr Presentation. Any info would be appreciated, even a rough estimate of value. I have shot 12 rounds thru it in twenty years. Previous owner only shot it a few times.
