Can a Sherwood Foresters enthusiast tell me please - is this badge an officer's one or would it be a variation worn by sergeants or a private purchase item perhaps for an OR's Coloured Field Service Cap?
It is generally of OR's quality and shows no traces of gilding or silver plate however it's central design is voided with a blue enameled backing plate as per an officer's badge.
The bottom scroll is affixed by pins rather than brazing, the lugs are short copper "D" loops.

Suggestions as to exactly what this badge is and period within the King's Crown "Nott's & Derby" scroll usage it would've been worn welcome.

Is it just a cheap metals version of the officer's badge?
