its gas tank, fork tubes, fender braces and brake backing plates painted in the Vincent Stevenage factory’s Chinese Red, the 1951 Vincent Series C Red White Shadow is the only one of 15 motorbikes produced to come in this rare, special-order shade. Confirmed by Vincent Owner’s Club as a true “one-of-one” Black Shadow variant, it comes built to ride – courtesy of a complete engine overhaul by Vincent maestro Mike Parti – with the modern additions of Amal MkII carbs, an electronic ignition, a two-step high-volume oil pump, and Carrillo connecting rods. www.bonhams.com
