"Elegant"vintage FP unknown maker?

[Lefty John]

Hello from snowy Milwaukee's Halloween
Hoping the expertise here will help me solve this mystery pen. Picked it up at a local rummage sale for $7, cleaned and filled it. Nib seems a little scratchy, but it is a fine nib (I believe), and I haven't tried tuning it yet. Writes fairly nicely otherwise!
I'm assuming from it's basic quality that it is probably a 2nd or 3rd tier pen, but I have not been able to identify it or find any others matching it!
Here are a few rudimentary images. It seems to be a marbled celluloid barrel style, with an aerometric filler system. The arrow pocket clip is slightly bent away from the body; I don't know if the clip style indicates a Parker. The marking on the metal filler button says "Trade Mark/ELEGANT/Made in Japan" (Eeek?). The nib is also marked "Elegant"; with a "W" inside a soft 5-point star, and "Special" with a number "3" inside brackets (?) just into the section.
Any of you experts run across this before, or hazard an educated guess? Maker & age?
Mucho Thanks!
John
