Looks like a nice, early Sprengpfeil to me. Better wait for the specialists' opinion, esp. for the Waffenfarbe. I can't say whether this is jägergrün or Beamten dunkelgrün. Doesn't look like Flugsicherungs-hellgrün (light green) to me from the fotos see here:
Don't know why the link doesn't work, it is on wikipedia, search for: Corps colours of the Luftwaffe (1935–1945)

I would say Beamte. According to the seller, "L.A Hamburg" = Luftamt Hamburg.
NEC SOLI CEDIT
Yes I agree, possibly Beamte, but still appears too light, maybe Jaeger perhaps...
Here are a couple of mine, my Beamte is a very dark green, and an Air Traffic Control/Radar Units coloured caps for comparison....
Excuse my ignorance but was is Beamte, I thought that was just another term for officer.
Thanks for the info. A rare cap or not!
