Beagle, you never fail to amaze me; the new phrase of the day is Beagle-eyed.
Cows Getting Bigger: spot on fella.
Brevet; I was devastated when I found out I would not get mine, although they would have been the RN "squashed moth" variety, I felt a large rug had been pulled from beneath me. The effort to get to where I did was immense and I take my hat off to those that made it further down that particular pipeline.
As for TCT wings, I can think of no excuse/reason for her to wear any form of military brevet irrespective of the era they are from. You can get away with wearing a uniform,medal or badge as part of a costume a la Cheryl Cole/Fernandez/latest hubbies name as there is no attempt to deceive. With TCT we all know EXACTLY why she wears them, she wants to be something which she clearly is not.
If the wings had anything to do with Amy Johnson then I believe they should be Air Transport Auxiliary ones; even so, these too would be an affront to all ATA pilots if worn by a walt.
