Hi,
You are quite correct, Fakhr El Kheil as a decendant of the Skowronek son Registan through the wonderful Sheikh Al Arab daughter Mahasin who was out of Kasbana (Registan X Resella), doesn't fit the Pyramid Societies definition of "straight egyptian" but then neither does Selimah's granddam the great Sappho (Blenheim X Selima), bred by the late Mr Musgrave Clark. Still Selimah looks from her pictures to be a very nice mare indeed.

incorrectly labelled or not , it makes little differance so far as the horse herself is concerned.
