On the background you can see 4 of the Afghans IMAM Ro.37 in the final stages of construction in the Capodichino hangar. They have only the rudder with the Afghan colors, in the Alegi’s book “Il ritorno del Romeo” there is a possible reconstruction of the appearance of the aircrafts: roundels on the wings but not on the fuselage and rudder with the Afghan colors.
