The speaker has been completely redesigned:

The case has light, age-related damage especially on the lower edges. These were repaired and repainted or painted over. Scratches were slightly overcoated on the top. Overall, a very nice looking speaker with black
Covering and perfect sound - as Hans Deutsch thought.
