Maker identification.

[Adrian]

I've been trawling through threads trying to spot a match to a maker logo but have either been unlucky and not found a similar cap or I'm seeing something that isn't there.
In my eyes, the maker logo inside the cap below looks like a head profile of a cap wearer facing left inside a darker circle or oval. It's a bit worn.
Can anyone help with a possible maker please?

Hello Ade,
looks like HNE - Naubert, see here: Nachschub NCO visor cap Hermann Naubert
or here: Private purchase medical NCO cap for rank of Unterarzt
