hey dont be gettin the wingmaster confused with the express. the express is always cheaper than the wingmaster. the old wingmasters are usually pretty pricey. if they are perfect conditon with box like you say youll not find one cheaper ina shop. i have a wingmaster magnum 12 ga and i give 300 for it and its not in perfect shape. mine has a 3" chamber and a 30" full choke bbl. i think it was made for turkey hunting in the 80's before choke tubes were popular cause the long bbl give tighter patterns and better range. if you like the wingmasters you saw buy one they are worth the price. the 28 ga book for $650, the .410 book at $550 and the 20 ga at around $400. $340 sounds like a good price on the guns. hope this helps
