Yes, the hammers are supposed to go over top of the barrels to hit a pin that protrudes through the side of case to the outside of the chamber to then ignite the primer. The current state when purchased was just the barrels forend and action I had to make the stock and find locks I used locks off a 10gauge that was deactivated so I would have to make new hammers to hit were the pins stick out.
I do know of the Kiln gun cases and they used to be sold so much that their were swagging dies made to make them fit contemporaneity 8 bore chambers. I have a group of shotgun cases coming from the UK including 4 and 8 bore brass hulls and was probably going to get either those or modify them and get them copied at a machine shop be about 150 per case. I was also thinking of tacking a 10 gauge base and useing compressed paper to build it up at the back and make the hull tube.
I thought about this but I do plan on getting myself a CNC machine for personal projects since i buy older guns and their are not any gunsmiths within 8 hour drive so i figured might as well get to doing it my self especial for eventually making myself my own double rifles one day.
I would figure out the gun before I worry about the ammo. Is there any pitting in the barrels? That would render a demascus gun a wall hanger as any rust/pitting can get between the welds and be much bigger then one would think it is forming a pocket.
No pitting in the barrels or outside the barrels and replacing the receiver is the only issue. It is a risk I am willing to take since these barrels are the best shape damascus barrels I have seen I am confident in the barrels not looney tuneing themselves.
I have one that may have been a 14ga at some point but it’s had a modern 12ga chamber reamer run into it. Easy enough to make cases for mine but I do like your idea sure beats turning the entire case.for shells, what I did was to turn a base from solid stock then expand some 1/2" copper water pipe to a sort of beer bottle shape and soft solder the two together. The gun and shells shown are 16 guage. At a guess you could probably make 8 guage shells from 3/4" copper pipe. Two important points re pinfire shells; the pins should be copper or brass to prevent damaging the hammer faces and/or the tumblers, second the pin is very close to the base of the shell; that means modifying modern centerfire cartridges would be extremely difficult. I used an end mill to cut a square bottomed recess that a number 11 cap sat in. I kept the pin in place with airplane glue. If the hammer strikes are weak, you might have to drill the cap recess all the way through then file the bottom of the recess flat so that energy is not used up forming the cap into a round bottomed recess
The green plastic case does not work well because the plastic case tends to come out of the brass base.

I was thinking of getting in contact with them for 4 bore cases for a different gun couldn't hurt it would just be down to lead times and price.
