I’m saying this is WW1 vintage, due to the ‘high prominence’ of the crown, a characteristic of the era.
A good used item with age and use tarnishing to the bullion wire work. Maroon velvet crown insert with matching wear.
One area of small none active moth to the badge centre barely visible.
Reserve complete with backing cloth and possible a vintage price tag in Shillings. If so a very expensive badge when new, possibly a stock code?
A superb looking badge.
