Similarly you can "google" Eukaliptus, Bask, Witraz, etc. My personal favorite, of the horses on your list is Comet. He was such a tremendous sire, across the board. To quote the above article - "There are also the legendary horses that one can¹t forget from this century, TRYPOLIS, who produced horses that are recognized for their stamina, good bone and racing ability, and, his grandson, COMET, who is deserving of an entire chapter himself in the Polish journals. He singularly crossed well with every line in Polish breeding, and represented the culmination of centuries of breeding. COMET had tremendous beauty, great structure, wonderful straight legs, nice short pasterns, a strong hip, and a substantial stifle muscle. COMET is now represented in Poland by the offspring of his grandson, PROBAT. "
Keep searching, there is quite a lot of information available. The Polish horses were tested on the racetrack, before being allowed into the breeding shed. They maintained performance testing of their bloodstock so that only their best bred on. They were not the only country to do so, but you will find all that out in your research.
