Colour
Black over tan leather

A rare Avions Voisin C28 Chancellerie, one of fewer than 12 thought to survive from an estimated production run of just 50 units built between 1936 and 1937, this example carries a C25 chassis identity it likely assumed after World War II to remain road-registered. Documented from December 1959, it passed through several French owners before entering the care of Jean Paul Dubroca, Vice President of the Avions Voisin Club. Between 2015 and 2019, the car underwent a comprehensive restoration by Carrosserie Tessier costing over €300,000, including a full engine rebuild, after which it won its class at the 2019 Chantilly Arts & Elegance.

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.
