There are inaccuracies in depiction of royal Yugoslav Hurricanes...
Yugoslavia imported 24 Hurricanes from Britain and further 48 were to be license build in our factories "Zmaj" and "Rogožarski". There were some differences between two batches. Imported machines were initially with canvas wings and two blade wooden propellers (first 12 examples) and remaining ones had metal wings and three blade variable pitch metal propellers. What is common to these imported machines is that the original RAF paint scheme (both A and B pattern) was kept. These aircraft are also immediately distinguishable by white roman numbers (I-XII) on the fuselage. National markings consisted of large "Kosovo Cross" roundels in four wing positions. No national flag on the rudder.
On the other hand, Yugoslav build Hurricanes all had canvas wings but three blade propellers. By the time when these were starting to be delivered new paint scheme was developed for our aircraft consisting of light blue undersides and three tone upper surfaces (olive green, brown and ocher). Also low visibility national roundel of reduced size was introduced in two wing positions. National flag was painted on the rudder. Under the flag there were aircraft data written in small yellow Cyrillic letters.
Royal Yugoslav Hurricanes never had yellow painted wing leading edges.
