Help to identify tunic

[Blitzvogel]

Hello,

Any idea what this tunic might be? Feuerwehr? Feuerlöschpolizei? The cut does look like DDR to my eye.

From the symbology of the sleeve badge, it's clearly for a firefighting service.

The tunic is not from the Third Reich or the GDR, though.

(Otherwise, I don't know.)

Many thanks Andreas!
