Check out Miraphone's new pistion BBb tuba based on the 191 but with pistons and an "American" twist...the new 1291. I don't think this is "old news," other than the rumors of it being made.
Here is a pic and a link, but beware that this new piston BBb info is only available on the German side of the site.
