Yardville
Looks like a running light is attached beside the license plate. Photos of this car were used in Superior's 1972 advertisements, albeit with an airbrushed 1972 grille. Photo from Steve Loftin. The NF license plate means "No Fee" for the vehicle license and registration as the owner of the vehicle was a non-profit. An ambulance that charged a service fee or was owned by a business would have had a commercial registration. And if the ambulance was owned by the town it would have an MG license for Municipal Government. Info from Rich Litton
