SOLD Nice older (1968-1973) Remington 870 Wingmaster in 12ga. The older "S" prefix serial number indicating the gun was built between 1968 and 1973. The SN is S991xxxV. Has a 28-inch barrel with Full choke. The gun is very clean. The receiver has thin bluing in some areas and scratches as seen in the pics, worst blue is the top area in the back of the receiver. The barrel looks a lot better with strong blue and just a couple areas where the blue has been worn away (probably from use.) The wood is fabulous with no dings, dents or scratches and some very pretty grain (not at all what you see on new Remingtons). I got this for a project and just need to cash out, so not looking for any trades. Just got this info from another member here at NWFA: Just FYI, acc. to The Book of Gun Values, your "S" serial number indicates a manufacture date of 1969.
