Wow, I totally forgot about that! There are a couple of manufacturers on there that don't exist anymore, but there are definitely ones that I'm not familiar with. I'll file that away to look at later once the backlog pressure goes down!
In terms of finding manufacturers by country, Filament Stories actually has that figured out, and her data is excellent! You can see it here: https://www.filamentstories.com/filament-companies/
