at Edward VII's coronation in 1902 "Aunt Augusta is photographed wearing the type 2 sized badge of her mother, the late Duchess of Cambridge.
This badge had been inherited by her sister Princess Mary Adelaide Duchess of Teck, then by her daughter May, the Princess of Wales in 1902. It seemed she loaned the larger badge to her Aunt.

I wonder what happened to the Duchess of Teck's own badge? Must have been inherited by one of her sons.
