This an Ercoupe 415-C (registration PI-C331) owned by Juan Antonio M. Llantada. The picture was taken in the 1950's at their private airstrip in Hacienda Refugio, Menchaca Hermanos, San Carlos City, Negros Occidental, Philippines. During afternoons they would fly the Ercoupe around the hacienda, nearby islands and the city just for a hobby. During that time the Menchaca's were the only one who owned an Ercoupe in the entire city. (dea - Note the Aeromatic self-adjusting prop on this Coupe.)
