A French market version of the Italian OM light truck, at one time very popular with French fire services as their PS first responder light pumper. These were around when I lived in France in the 1970s.
This came in two door cab and four door cab versions, as well as a factory van, with gross weights of 6, 7.5, 9 and 11 tons. Wearing OM, Fiat, Unic or Magirus badges it was widely used by fire services in Italy, France, Germany, Belgium and the Netherlands as a light to medium pumper, compact TL and for a variety of rescue and support or special purpose units.
