All of my pinfire double rifles and guns have had damascus barrels, most of them Bernard pattern except for the Purdey, and those tubes were forged in-house.

The old cartridge bore-rifles are cool as it gets - and it's good to know they're an approved werewolf remedy!

On the absence of firing-pin notches on the barrel breeches, they were typically dovetailed with solid steel or the barrels would be faced off and rechambered, the lumps and hook set forward to re-set headspace.

The pistol-grip is steel, part of the long trigger-plate tang.

On the bullet-casting scene in the movie trailer, there are more than one cool vintage rifle featured in the film - likely for a different rifle!
