Clark was not happy with the result, and the two breeders had a somewhat cool relationship after she purchased the stallion. While Count Potocki apparently found Skowronek unimpressive as a colt, having sold him to Winans for 150 pounds, the gray became a spectacular stallion and was named "Horse of the Century". Lady Wentworth later turned down an offer of $250,000 from the Tersk Stud, and bragged that she once received a cable "from the Antipodes" addressed to "Skowronek, England." The outcross of the Crabbet stock with Skowronek was extremely successful, and the resulting animals not only sold throughout England but were exported to Argentina, Australia, Canada, Chile, Denmark, Egypt, France, Germany, Israel, the Netherlands, New Zealand, Pakistan, Poland, South Africa, Spain, Russia and the USA. The Skowronek controversy Lady Wentworth herself was satisfied that Skowronek was a purebred (or asil) Arabian, tracing his pedigree and strain to several reliable desert sources. In the General Stud Book, however, Skowronek's pedigree ends with three grandparents. This has led some Arabian enthusiasts to question if Skowronek was in fact a purebred. His sire, Ibrahim, was desert-bred and imported to Poland. His dam Jaskoulka (variously known as Yascolka or Yaskolka) was a Polish-bred Arabian. However, while the Poles had bred Arabians for centuries and kept careful pedigree records, they also crossed Arabian stallions on Thoroughbred and other non-Arabian mares. In addition, some breeders used different terminology to distinguish horses bred in the desert and imported to Poland from the descendants of those horses bred in Poland, with translation issues leading some English language researchers to argue that second and third generation Polish-bred purebred Arabians were not actually purebred. For these reasons, some people argued that his dam was not asil. However, research of Jaskoulka's pedigree shows that her sire Rymnik and her dam Epopeja (also spelled Epopeia or Epopya) both traced to Abbas Pasha horses. Nonetheless, due to this controversy, some private breeders' organizations, such as Al Khamsa, exclude descendants of Skowronek. The Depression, World War II, and the postwar years Crabbet's peak year was 1929, when over 30 mares were bred. But as the Great Depression deepened, it affected Crabbet Park, with Lady Wentworth only breeding 8 foals in 1932, and 2 foals in 1933. To reduce the size of the herd, she made major sales in 1936 to the Tersk Stud of the Soviet Union, selling 25 horses, including the beautiful
