What companies build a flintlock SxS or O/U?

I know there is the classic single barrel fowler. But two and 4 barrels have been around for a long time. I have seen them in museums but only Pedersoli has made reproductions to my knowledge unless the occasional old French or English shotguns in need of repair/wall hangers. So is there anyone still making them besides soli?

Your guess is as good as mine. I suspect Pedersoli is the only one. SXS flintlock shotguns are typically a custom item, it seems.
