Bask, bred at the Albigowa State Stud in Poland, was a bay Arabian stallion who was imported into the United States in 1963 by Dr. Eugene LaCroix of Lasma Arabians and became a major sire of significance in the Arabian breed.

Witez II was a bay Arabian stallion foaled at the Janów Podlaski Stud Farm in Poland. He spent his early years at Janów at a time when Poland was under occupation by Nazi Germany before ultimately arriving in the United States in 1945, where he lived for the remainder of his life until his death. His name came from an archaic Polish word meaning "chieftain, knight, prince and hero."
