I wish I knew more about spanish bloodlines, I thought there was a fabulous group of horses for sale at the end of last year, gerald? would have had any of his mares and the stallions! (If I was twenty years younger)
Without actually working it out I would guestimate that most Egyptians come in at around the 25% Crabbet mark and the Crabbet/Old English dam should be in the 90%+ range - meaning this mare will be about 60% ish. Hope that helps.
