Recorded originFrance
ClassOpen passenger automobile; exact factory bodies unresolved
CID's technically ambitious larger car used rotating sleeves rather than poppet valves and was explicitly not a Knight-licensed sleeve-valve design. Track was 1,320 mm, tires 815 × 105, and the quoted French price of 8,000 francs excluded tires. Body catalog, output, performance and survivors remain unresolved.

Likely only a handful; no dependable count survives.
