Hi, from what you've said, I'll bet your gun is one of the Savage Fox guns that is in fact a fancyed up Stevens BL. The vent rib and engraving on the floorplate (I'll bet it's a Fox)is common to the Model B and BSE (there were other variations also). The only thing these guns had in common with a AH Fox is the name.
A picture should confirm what model you have.
There is not a great deal of demand for them other than shooters. They are good solid guns, nothing fancy, but a true Fox or even a Savage made Fox from the 30's they are not.
Best of luck to you!!
