Oh, I know all about these headpieces and have been studying them for years. It's just that the Raven Bar piece is the elusive one even to get any pics of, period. I only have a clear shot of the front of the piece but you're telling me that the writing on the feather area is on the back only?
Correct! The Hebrew letters/symbols are only on the wings of one side, of which are never seen onscreen (Not sure why!). I've got reference pics of the original prop that are as you say very "elusive". So, this will be an accurate interpretation of the original!
