1935 Auburn 851 Custom Speedster (un-supercharged, naturally aspirated)

1988roadUnited States
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.

This car's public record is built from its auction and competition history. Register your ownership and privately add your own records to make it a verified Legacy Metrics passport — provenance that backs your car's value at sale and gives your insurer evidence to price against. Roy reviews and verifies every registration personally.

Each chassis record is compiled from public auction archives and links to its source material. Ownership, competition and maintenance entries are extracted from those catalogue listings by an LLM, which can make mistakes — please contact us with any corrections. The summary is Legacy Metrics’ own writing; we do not reproduce catalogue text.

“Full” and “partial” documentation labels indicate how well each entry is corroborated in the underlying sources, not an audit of the car’s physical paperwork. Names of recent or living owners are withheld for privacy.
