[Dénes Bernád]

Those spotted "Italian" airplanes were most probably Hungarian ones, and the "Macchi 205s" were, in fact, Bf 109Gs. Because the Hungarian tricolour (red-white-green) was painted on the tail and horizontal stabilisers, they were often mistaken with Italian airplanes.
That day (16 July), the Hungarian 109s' did not suffer any combat losses, although they claimed two B-24s and a lone B-17 south-east of Vienna, all reportedly flying unescorted.
