A guess - they are like the additional markings borne by aircraft of the
Polish manned squadrons in theBattleofBritain- perhaps some unofficial

Thanks, Sounds very reasonable even I could not find that mark via
Google.

As noted in the other group, this is also the naval / air signal flag
for
the letter "U" . This flag signal means "You are running into
trouble."

In any case, I see it as a private overprint, either to remember
Polish
pilots in the Battle of Britain but more likely, giving a 'black
humour'
warning to the Nazi pilots in that battle that the spitfires are after
them.
