Joseph,
I have saved many of these. The barrels are cut, but may be usable. Some soldier in those muzzles would help and make it look better. I have a set of 20" damascus barrels that were cut and work fine. How are the bores? Any pitting?
The price of that hammer screw on EBay is a little steep. There are one or two different threads. I have had some hammer screws that were interchangeable and some that wouldn't work.
Try these first;

It is nice to bring one back. Good luck and feel free to reach out with any questions.
