Bi Metal Cast Musicians Badge - Unidentified

A well made and early item of two part construction with King's crown and two original lugs to the reverse. To the centre of brass star is mounted a St George slaying the dragon. Possibly a civilian band item / youth orgianisation badge. Circa 5.5cm tall. I have seen a similar badge with a bi-metal Prince of Wales's feather plume to the centre which leads me to suspect this was worn by some civilian organisation with representation in each of the Nations. The St George presumably representing England.
Any information welcome.
