In the USA, World Champion 2-year-old trotter on half mile track. At 2 undefeated in 10 starts. At 3 winner of 8 of 12 starts. Exported to France where he won 24 races. He was one of the better horses at the time and managed a fifth place finish in the 1938 Prix d’Amerique, where he was the pre-race favorite together with another US-born trotter, the legendary mare Tara. Calumet Delco’s most famous race in France is probably the 1937 Grand Prix de la Ville de Nice, where he had a 100 meters handicap in the 2500 meter long race (1 9/16 mile), yet ended up losing by only a nose, and setting a French record of 1.21,4 (2:11) in the process. Several horses in the the French stud book has Gael (fr) listed as their sire. In 1992 it was made public by Albert Veslard’s son that mares owned by his father that were due to be covered by Gael in 1937 were in fact covered by the American stallion Calumet Delco instead. The subsequent foals by Calumet Delco were registered as by Gael because the Stud Book for Trotteur Francais was closed at the time to all outside blood. As there are no officially registered foals by Calumet Delco in the Stud Book du Trotteur Francais, his line doesn't officially exist, however its existence is commonly accepted in France where the leading trotting magazine, Trot Information, refers to this line as 'Lignee Calumet Delco'.
