Could I ask you to elaborate on why they are desirable? I mean I know they are still a Fox. But the reciever's are blued, minimal engraving etc. The pictures on the Fox site remind me of the later Fox model B's. (which you can't hardly give away). I am interested in this one only because it is a 16 and reportedly in "excellent" condition. The current owner is clueless as to what he has - only that it was Grandpa's gun. Are they desirable because of limited production or .... something else I am missing? Price is $700.
