Bred by David Griffiths, UK. Owned by Frongoy Stud (Jones Bros). Mathrafal has been the most influential Cob Stallion in terms of siring potential future Royal Welsh Champions. Between his progeny they represented a total of 13 Championships. Mathrafal duly won a first prize at the 1937 Montgomeryshire Show. At the 1938 combined Royal Agricultural Society of England and Royal Welsh Show he won the young stock class and went on to win the male championship. His show career was then interrupted by the war years. He won a second prize at the 1947 Royal Welsh Show, third in 1949, second in 1950, third in 1951, champion in 1952 and fourth in 1953.
