I’ve seen them before but I literally can’t find it

I was watching a music video and it featured a Tuba like this. It looks like it has 6 rotary valves. I can’t find anything about it

I got this on a auction on Shop Goodwill and everything looks great. I already have a 42B and just wanted and regular tenor and saw this. Saw it was a Bach and liked how it looked. But now I can’t find anything about it no reviews or anything. I know it’s a student horn so I know what I’m getting. Just can’t find anything about it
