I picked this up, and at the time thought it might be a beret badge. Obviously upon receipt it's way to big for that, being 80 MM x 68 MM. So, I then figured it was a blazer badge....until I was looking through David Parsons' book - "A Collectors Guide to Badges, Emblems and Uniforms of the Royal Air Force and Associated Organizations", page 594 in the section on prototypes. On that page there are several badges, and upper left seems to be like mine?
I would value any opinions and/or thoughts, or information on it.
Thank you,
Terry
