Dryfly Tubefly--Exists or not?

A dryfly tubefly.........

Is there such a thing?
Has anyone seen or read or heard about a reference to
the idea of a dryfly tubefly before?

........I made the claim I invented it.
Someone else challenged that claim, but
supplied no counter example.

So I'm (more than mildly) curious.
Maybe it's out there and I'm just a dumbass.
But I sure haven't seen it.

What about you?
Who what where how?
Help me out.

Hi,
here is a link to a Finnish website:

"Mr.Pompero" has tied some floating tubeflies, if you care for
translation let me know.
