If the stock was unmolested - I'd say about $2500-4000 without a closer inspection, and without knowing the manufacture, and type of barrel metal.
Older four barrels in any condition are pretty rare - it's a collector piece at least.
With the stock "work" - I think it's closer to $750-1500 as an interesting piece until something better came along.
YMMV
