...Hoshino Kougyou was a factory, and the kits sold under many names - here in Europe "Aria", "Santana" and "Luxor" amongst others. And sometimes just "Hoshino"....
Jon, I appreciate that you have a soft spot for Hoshino, and all of your information is correct, but: 'Luxor' was made by Tromsa, a German drum manufacture, and not by Hoshino. (This I know from a Germany guy's website about Tromsa.)
Or have there been two different lines of Luxor on the market/s?
