ARU or HRU badge, help wanted

[Peppe864]

Does anyone know anything about this badge? Same size as a NSDAP membership badge.

I haven’t seen this badge before but it brings to mind the Turnerbund organization.

My personal feeling is something towards Eastern Europe, maybe Hungary.

Probably Third Reich-related or that time era, due to the symbols.

All info welcome.

PS.
I have a fetish for uncommon/strange badges and pins!
