If it needs a stock and forearm, it's not worth much. If it is a boxlock with fluid steel barrels, fully functional and OK'd by an experienced gunsmith, it would be worth $200+ as a shooter. If it has laminated barrels and side hammers, it might bring $125-$150 as a mantle decoration. Like any other machine 80+ years old, parts are where you find them. Your local gunsmith can probably find wood that will fit or can be made to fit. To be a decorator, it would be enough to repair the existing stocks with Elmer's glue and wood filler if that is possible.
