"something that had not been introduced...."

Did the Ho-1 precede Robert Kronfeld's huge Ku-4 Austria or 1932?
According to Martin Simons' description of it, the twin rudders only
moved outward and you used one at a time to turn, or stood on both
pedals to use them as brakes. The only problem is that didn't really
work very well...

Seeing Simons says the Austria was the first glider to have any form of
brakes or spoilers it follows that the authors of "Nurflugel" were mistaken.
...

"Something that had not been introduced" is ambiguous. The
'something', maybe 'spoilers', or the 'something' may be twin
rudders that both open outward to act as brakes as opposed
to other sorts of spoilers or breaks.
