This omnibus is without doubt a Delahaye 131, which was offered commencing in 1935. In 1937, the Delahaye 131 N followed which was propelled by a Renault engine.
Most probably this omnibus is a Delahaye 131 N which was manufactured starting in 1937. The year of construction of the illustrated vehicle was 1939 or 1940.
An omnibus of the same type. The rims seems to be typical for Delahaye. The design of the radiator grille is very similar to a picture from a Delahaye omnibus brochure from 1938.
