We purchased Bel Air as an unproven herdsire based on his genetic lineage that traced back to 4Peruvian White Knight, his lovely conformation, and his low P-S spread of 3.9! He was also able to retain fineness (22.9 - 19.0 P-S spread at two years of age). Bel Air went on to produced a number of offspring that we still have in our herd today. His most notable traits passed on were luster and that narrow P-S micron spread.
