If you knew the manufacturer that might help finding someone to do it. My uncle had lilja to turn one down. Super fast and no drama.

I was going to have a Pac Nor turned down and they were happy to do it until I mentioned I had it flutted. The flutes can mess up the tooling and they didn’t want to mess with it. I don’t blame them. If you don’t know the maker then I would say good luck finding someone like grey dog said.
