1935 Auburn 851 Custom Speedster (un-supercharged, naturally aspirated)
- Engine
- Naturally aspirated straight-eight, no supercharger, with dual-ratio rear axle
- Colour
- 'Duck Egg Blue'

A rare factory-built un-supercharged Auburn 851/852 Boattail Speedster, this car was assembled in the original Auburn, Indiana plant rather than the Connersville facility, apparently for exhibition purposes prior to the availability of supercharger equipment. Its Custom trim specification, original serial and engine number tags, and unmodified block stamping make it uniquely documented. The car passed through several notable American collections before receiving a body-on-frame restoration finished in Duck Egg Blue with red leather interior.
