What Insignia belongs on this Albert Kempf Alkero Visor Hat?

I see photos all over the Internet of this hat, but never with insignia. What would go on a hat like this?

The missing insignia is a Dutch lion badge.
It is a Dutch visor.
An example for sale in the link below.
The chinstrap and side buttons are replaced on yours and not Dutch.
