Swiss Black Powder, but which one?

Everybody is praising Swiss Black Powder, how consistent it is, making minimum fouling, easy to clean, uniform and high velocities, etc. Although more expensive than others, but for competition is a top choice.

Having in my area just Czech VEZUVIT and Slovenian KIK (this one just occasionally) and learning from other shooters that they are not great for revolvers, I started looking for Swiss black powder. Unfortunately, no luck. I was thinking about importing it from other EU countries, but was told to forget it, too complicated and too costly for an individual.

Today I found that my local dealer is importing Reload Swiss smokeless powders https://www.reload-swiss.com/en/reload_swiss/index.php . Well, if they could import those, why not Swiss Black Powder. So, I started searching internet to find more about it. Than, lo and behold, I found no less than 3 different brands of "Swiss Black Powder":

- "Swiss black powder" from LHS Germany, https://www.lhs-germany.de/en/powder/black-powder/swiss-back-powder/

- "Swiss Black Powder" from Aubonne Black Powder Company, Switzerland, https://schuetzenpowder.com/swiss-black-powder/

- "Swiss Black Powder" from The Maine Powder House, Lewiston ME, USA, https://mainepowderhouse.com/product-category/black-powder/swiss/

Question: When you are talking about SWISS BLACK POWDER, which of those 3 you are using?

Thanks Mizar for suggestion, trying to figure out how to update my profile. Yeah, I am now in Croatia, retired, after 36 years in Canada.

So, If I understood you correctly, manufacturing facility is Aubonne Black Powder Company (Poudrerie D'Aubonne S.A.), Switzerland, and others are just distributors for the same powder, despite different labels!? Regardless, I just found that for UK, importer is Henry Krank, and from their website I could see they sell powder in original package. This is important info since shooters from UK told me, for best results and minimum fouling, use "Swiss Black Powder" so I will direct importer to go to Aubonne directly.

As for import locally, of course, this will be larger batch for number of shooters, not just for me.
