SP: Double Berger cutting point. The earliest source known to me

find this anywhere in the 1911 NP column. (2023-11-16)

Years: 1928
TODO: Quelle prüfen - weder bei visueller Prüfung noch im Schwalbe-Index für die Jahre 1928-1930 konnte die Aufgabe gefunden werden.
Das Rätsel ist gelöst: Die Aufgabe erschien nicht in der Schwalbe im Jahr 1928, sondern in einem Sonderheft der Schwalbe am 06.07.1965 als Widmungsaufgabe von AG zum 70. Geburtstag von Dr. Wilhelm Massmann mit der Problemnummer(!) 1928. Den Abdruck dieser Aufgabe fand Carsten Ehlers.
Die Quelldaten in der PDB sind nun richtiggestellt worden.
