I found inscriptions at the inside, these identify the owner.
Every boy in The Netherlands received a registration number around his 17 birthday, starting in 2019 this will be also true for all the girls. The conscription still exists in The Netherlands but since 1996 no has been called in to service anymore. The Netherlands forces are only professionals now.

The inscription shows SW72 Schubbert Werke 1972
I also have in my collection a beret worn by the KMAR in the seventies:
