Bottom bracket identification

Hi experts, does anyone recognize this bottom bracket or have a clue on brand?
Axle is not magnetic, so suppose worth keeping.
Length is 107 mm, probably from end of 90s. Still works fine.

I was just stripping a 90s Mountainbike that’s been sitting in my basement for a while – got it used and now wanted to reuse the parts for another project.
When my wrench slipped I decided to stop for now.

It’s a German aluminum frame and it came from Germany – original owner not known (to me) – the family I bought it from clearly were just riding it around town without knowing much about it.
