RAPC Oddity

I've had this badge for some time, but I've always been at a loss as to exactly what it is. Cast brass with three lugs, but oddly they point inward toward the crown, i.e. N-S, NE-SW and NW-SE. Obviously a theatre made badge, but can anyone explain the fixing orientation. As always, many thanks in advance.

The lugs are perhaps angled for easier insertion of cotter pins when the badge is being fitted to headgear and pins being inserted when the headgear is held upside down?
