Might be willing to spend some money…

I believe most people here would feel you would be upside down on a complete restoration. Any work done should come after first having the barrels checked by a competent gunsmith, knowledgeable in composite barrels, and deemed safe to shoot.
If the barrels checkout okay, you could possibly get the stock repaired by a competent stock smith to a point of making the gun shootable again.
Useable hammer gun stocks are difficult to find and fit. Having a new stock made in itself would likely exceed the value of the gun. There are good gunsmiths, stock fitters and barrel experts available and somebody here could provide you with contact info at your request.

If your serial number is 13787, there are records available for a PGCA letter. How did you arrive on the "DH" grade? As another poster indicated, your gun is not a DH. The condition of this gun would suggest that the barrel interiors are abused and not suitable of restoration. Without good barrels, restoration is not possible.
