Typical of the hand finishing on badges made by this maker.
Mine has been posted here.

A nice sheet metal hinge Wilhelm Hobacher, Wien ISA...
The sheet metal hinge version from this maker is known for the heavy filing marks your example displays.
In my studies of the WH variants, I have found the block hinge examples usually have a more honed or polished reverse.
