The Pierce-Arrow Model 66-A-4 is among the rarest and most coveted Brass Era automobiles, with only 14 known survivors from a production run of roughly 1,250 cars built between 1910 and 1918. Chassis 67219 is powered by an 825-cubic-inch T-head inline six, one of the largest engines ever fitted to a production car. It carries a period-correct cast aluminium body fabricated by restorer Carl Amsley to factory specifications, and has been the subject of a fully documented restoration. Recognised as a Full Classic by the CCCA, it has accumulated reliable touring miles in HCCA events.
