Interesting image, taken, as the caption states (for a change) during Nationalist service following the type's capture after the Republicans surrendered at the end of March 1939. Photos of the Tupolev SBs in Republican service are not too common as photographing them was forbidden and most of the images of them seen in Republican markings came after their capture. Note the Caproni Ca 310 in the background with the white tail. The aeroplane was nicknamed the Martin Bomber in service.
