I had a PowerBronze (UK) screen which had the nostrils and a flip-up lip - like the original - but it was a good bit taller (5 inches I think). I was 6'3" at the time. (I'm shrinking !!)
Link showing the +3 and +5 inch models . They appear to be still available.

[edit] found an old photo of it on my old ST1100AY with the powerbronze +5 fitted.
I like it so that I can see over the top, but the airflow is directed over the top of my helmet. The screen flip-up does that.
It resulted in a screen riding position which I also have on my ST1300 - see avatar. Looking over screen. Flip up pushes airflow over my head. The original screen doesn't do that on the 1300. If I look over the screen, the air goes straight into my face. I don't often ride with visor down.
