As far as I remembered is that the AAF left only two or three single seat MIIIEA plus the single 2 seater MIIIDA at Mariano Moreno AFB where the Grupo VIII was located at that moment in peace times.
The same happened in Tandil AFB where 3 two seats IA Dagger B and 2 or three single seat IA Dagger A remained at war time for Buenos Aires Air Defence role.
