- Colour
- Black with red striping

This 1929 Stutz Model M supercharged coupe, chassis M-C-31312, is one of only three known surviving factory-blown Stutz automobiles — built to compete at Le Mans and bodied in Britain by Lancefield for London broker Brainsby-Woolard. Its centrifugal supercharger produces an estimated 185 bhp. After decades hidden in a Vermont barn, the car was spectacularly revealed at the 1996 'King Stutz Tomb' estate auction, subsequently restored twice, and has accumulated an exceptional concours record including Best in Class at the 2000 Pebble Beach Concours d'Elegance.
