When Czescholovakia was occupied by Germany in 1939, no less than 21 Czescholovak fighter squadrons were flying this plane. Many of these fighters were incorporated into the Luftwaffe. Your photo should depicted an Avia just after this change, with the Czechoslovak flag still on the fin, and the German cross already applied.
This fighter fought with Slovakia and Bulgaria against the Soviets, and a few were even put into action against the retreating Liberator of the infamous Tidalwave bombing on Ploesti, the 1st august 1943.
the luftwaffe used them as target tugs with raised cockpits (kinda like an angled bubble canopy with frames) and romania used them against b-24s bombing ploesti but thats all i know about it

For your information, Rumanian Air Force never user the Avia. The backbone of rumanian air force was made of IAR 80 and Bf 109. They used in the early part of WW2 an aircraft quite similar to Avia, the polish PZL 11 and PZL 24 but none of this saw action against the american bombers. Only the IAR's and Bf's were used to defend the Ploieshti oil fields.
