Well its a police helmet, but after all. The cocarde indicates Baden (brass with red ring). The lower part of the two-piece plate is missing, do you have any references about that? Could it be similar to the prussian model (Example) which would fit the crown nicely?
There is a slight inward dent on the right side, I guess I will approach that with the Goretex-method.
