Ever tried a miraphone firebird?
Or a B&S Symphonie?
I wonder what a valve block with progressively increasing tubing sizes looks like for those BIAS acoustic measurements?

One of he Chinese manufacturers is now making a knockoff with those five bore sizes. It's not a complete copy, and the mouthpipe on that copy doesn't begin as small as with the original.
