Man, what a google trap! Def. spent at least an hour and a half total over the last few days to try to find this thing, but so far, still no luck. It does look vaguely familiar. The writing is just too unclear to help.
Things it could be:
A nozzle of some sort? Hose, shower, fire?
A vintage hair dryer diffuser?
The more I look, a plastic shower head seems very possible. I will post some pics if I find something closer. TRYING ED!
