Help to identify stahlhelm stickpin

[Supernaut]

Hi! Please help me to determine the identity of this stickpin, it has a stahlhelm on it but I have no idea about to which period & organization belongs,no maker mark and based on the manufacture I guess it can belong to 20-30s period. Any opinion welcome
