Chassis number 10431 is the sole known surviving 1913 Pierce-Arrow Model 48-B-1 Five-Passenger Touring with aluminum-over-hardwood-frame body construction, distinguished from the marque's more common all-cast-aluminum coachwork. Long associated with prominent American collectors, the car was comprehensively restored by celebrated Pierce-Arrow specialist Eric Rosenau, earning Best in Class at Pebble Beach and the Bernard J. Weis Trophy at the 1995 Pierce-Arrow Society National Meet. It has accumulated around 4,200 miles under subsequent careful stewardship.

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.

“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.
