Well it need not be just the machines what am I am trying to say is anything that would make the gun better should be used ,I was reading on Fabbari shotguns a while back,they for sure aint ugly.

Also based on what I have been reading recently I dont see any innovations being made with regards to double rifles recently,most of them were the ones that were made a century back.It could be because now its become a far more niche product compared to what it was a century back .
