They were made through the 70's. Price can range from $80 - maybe $200, depending on the condition and what one is willing to pay for them. Most you'll see on here are in the $120-$160 range..usually shipping included. Great single shot in my opinion. The plastic piece that holds the forend on sometimes breaks, kinda common, but not with all. Basically a "deluxe" version of the winchester/cooey 840 and/or winchester 370. I personally buy them up when I come across them, only if in very good++ to Excellent/ as new condition. Something about the older singles that I like, so I collect them. Cheap gun, but for the most part, built to last if looked after....like just about anything.
