Hi Boris,
Above the War Fronts shows 3 balloons for Ancilloto and 5 (one "round balloon") for Baracchini but only ONE of the five was confirmed.
Other Italian pilots had single balloon victories too.
I did not see ballooon victories mentioned for the Russian aces but I have seen some time ago a report that Russian aircraft destroyed a German balloon and think that was not the only case. Maybe the Russians Air Service did not count balloons (??) or the reports vanished.
Maybe another Forumitee can help you with examples of German or Austrian balloons destroyed by Russian aircraft.
