BriscoeRapidelivery
Separately advertised light commercial derivative of the B 4-24 passenger chassis, promoted for economical rapid delivery and night operation using electric lamps. The high enclosed body used large one-piece panels of waterproof Vehisote rather than conventional all-wood construction. It shares the passenger model's chassis and engine, but its recurring Rapidelivery name and dedicated business-market positioning justify a searchable model entry. No payload rating, cargo volume, price history or surviving chassis total is securely documented.
Dates with their meaning intact
This record contains useful sourced evidence, but it does not yet meet the reference-ready standard. Still needed: attributed imagery. Fields we cannot source stay empty rather than guessed.
No separate Rapidelivery total survives; included in annual Briscoe company production.
