Jan, did I understand correctly that the link posted by @scwells is the story of the pilot who owned your jacket?
Yep, that's his obituary. I'm going to be posting a much lengthier discussion of his life in next few days (I'm part-way through writing it).
They have very pronounced characteristic points or lobes, however I'm not sure if they're larger than say a star sportswear?
Agreed - I'd characterize the Monarch collar as average size, but the shape of the collar points/lobes makes it look almost as big as a Rough Wear collar.
