This plane was inspired by WWII planes.
It was designed in 1943 and built with local wood. As the in line engines were not obtained these had to be replaced with radial ones.
A hundred units were manufactured and joined the attack squadrons of the FAA.
The painting shows the famous attack to the VII Brigade, home of the fighter interceptors when during an exercise the Calquin evaded the radar chain and the fighters and bombed the hangars and runway of Moron with bags of flour.
