Who guaranteed him 100% Egyptian? If he has lines to Ferzon, Azraff, and *Carmargue.....and those are in his pedigree I see..... those are not Egyptian lines. Someone may have mislead you, altho he does have quite a bit of Egyptain in his lines, he is not 100%. Ferzon and Azraff are Crabbet bred horses. And the mare *Estopa, she was Spanish.
Gosh, for the difference in type.....well, in a very quick nutshell, and this is only just very general.... the Crabbet horses came from England, are very athletic and are great performance horses. The Egyptians tend to be somewhat lighter in bone, and a bit more of the "halter-type" horse, altho not always, depends on the bloodlines..... And the Spanish are very exotic looking and very typey. Polish tend to be a bit more muscular, and are also very good under saddle and do very well in performance. These are just the tip of the iceberg.....all lines are fabulous, and they all sort of have their special thing.
