I agree that we need a good shot of Princess Benedikte's brooch. Note that the centre of the illustration clearly states Rifle Brigade.
Edit: I feel I need to add that the piece might have been altered, though that seems an unnecessary, perhaps odd, thing to do. It was labelled as a pendant so perhaps the crown element was switched when turning it to a brooch. I know that illustrations are not always total copies but these appear to be quite reliable.
