Probably $600-$800. The front end with the WS-1 Barrel is indeed a skeet barrel (skeet 1). Value will hinge a lot on the quality of the wood. Presentation grad wood could bump it as high as $1000. I would have a gunsmith check headspace on both barrels. The skeet barrel may not have been fitted to the receiver. If the second front end carries a different serial number it is not factory original.
