'The Good Companion Two-Mover' gibt als Quelle an: "3002 G.C., July 9th, 1921", tatsächlich steht das Problem aber auf der Titelseite des G.C. Folder vom August 1921.
Evtl. wurde das Problem auf dem Good Companion Day, Atlantic City, N.J., July 9, 1921, präsentiert, oder es gab anläßlich dieses Ereignisses eine Sonderausgabe?!

Die Lösung wurde in SE nicht veröffentlicht, die Schachecke ab 01/1992 eingestellt.
