What is "naborr"

Naborr (April 3, 1950 – November 9, 1977), originally named Nabor, was a gray Arabian stallion foaled in Russia at the Tersk Stud. He was sired by Negatiw, a Russian-bred stallion with Crabbet ancestry, out of the Polish-bred mare Lagodna. After establishing himself on the race track and show ring in the former USSR, Naborr was exported to Poland, where he lived for seven years, and from there was purchased for import to the United States by a wealthy Arabian horse breeder from Arizona, Anne McCormick. Upon her death, Naborr was sold in 1969 to Tom Chauncey and Wayne Newton for $150,000, which was at the time the highest price ever paid for an Arabian horse at auction. He went on to become a leading sire of champion Arabian horses in the United States and Canada.
