Home Forums Hunting & Shooting Hunter's Campfire Browning Superposed Stock Question

I was trying to find a stock for a Browning Superposed and got what I thought was the correct stock. Do any of you know if the stocks changed slightly with different eras or DOM's? I even tried finding the part number stamped in the tang area (HX3643) and came up with a blank. I don't believe this is a Citori stock but it is a Browning O/U or some sorts. Any help would be appreciated.
