Thanks for the vote of confidence - that's an older bike than the bike boom bikes I'm familiar with. We need @juvela to see this - maybe he'll get the flag and visit this thread.
I can't identify the head badge, and I'd bet he probably can. I would guess it's a wheel and wings, but I can't identify a maker from it.
With that fork crown, I'd also bet prewar bike - great lugs, great fork crown - very high quality.
Definitely believe the bars are old-style Cinelli
