How can you tell if a baroque horse is a Andalusian, Lusitano or lipizzan?

I have a chance to buy a Baroque horse for $700.00. She is 18 years old but has no papers. She is white with a black mussel, thick neck, white mane and tail, looks like text book Lipizzaner. I want the horse for the horse she is I was just curious if there was a way to tell which is what. She is 15hh and 1200 lbs.
