S&W 36: Square Butt, Flat Latch, Diamond Grips, Pinned Barrel, SN 149XXX indicates circa 1958 manufacturing date. I'd rate this a 95% gun, it does show evidence of having been handled and carried, such as minor finish wear on the muzzle, tool strap, bottom of trigger guard, and minor freckling on the back strap. I tried to show these areas in the photos. There is also a minor pin head rust spot under the top edge of one grip. It locks up tight, and the action is smooth. Price reduced to $600 shipped from my FFL to yours or trade for a S&W 49 or 649.
