English British National Fire Service pin WWII era original NOS

Description

This is an original WWII era British National Fire Service pin. I think this is a hat or cap pin. It secures in the back with the early style clip.  It is NOS and unissued.  I put the penny in the picture for size reference.   Great item for a WWII, Fire Service, or Civil Defense collection.
This is a liquidation item and it is sold as is with no returns.
