I believe I can see Bernard pattern Damascus beneath the patina. You might be able to find an old set of Parker Bros. Bernard (CH) tubes that could be sleeved
into the original tubes. You might be able to cobble together a full length rib by splicing the Daly stamped section onto a nonoriginal rib. You might be able to find a set of diamond grade 10 gauge barrels( I sold a 32” Bernard set ~ 15 years ago)
A lot of “ might be’s“ here.......
If you have the time to spend on researching and acquiring the needed parts, the resources to engage the necessary gunmakers/ craftsmen, and the desire & patience to see through your project to fruition, I say “ damn the torpedoes”!
The key decision is whether you want to do a true restoration, or just “ salvage” what used to be a very special piece of Prussian craftsmanship.
If you choose restoration, be prepared for a long journey that you may tire of before you reach your goal.
Best of luck with whichever direction you choose.
Best Regards,
