Research Dossier (Reference Facts Used)
Avions Voisin C3 (1920s) quick facts used by this generator:
- C3 family commonly cited with ~3,969 cc sleeve-valve engine and ~80 hp in touring form (auction/reference listings). (See RM Sotheby’s C3 listing + C3 spec PDFs.)
- Voisin’s brand legacy notes include a 1925 C3 Cabriolet winning major concours class honors (brand legacy summary). (See Avions Voisin page.)
- Later Voisin C23 (1930) was 3.0L inline-6 sleeve-valve ~80 bhp, ~120 km/h; included here only to prevent spec-mixing and to keep the build historically consistent. (See RM Sotheby’s C23 listing.)
