Hmm this is a head-scratcher. I tend to agree with Adrian that the bent bracked must not be as crooked as it currently is. In fact the pictures and video make me think it might be straight with slightly curved edge contour:

However I’m having trouble make sense of the surrounding pieces. Is it possible that the upper and lower arms (yellow) aren’t directly on top of each other but slightly off-center to make room for the bent bracket to be straight?
