Dan-San, trust me, I am able to use a dictionary myself. Really. Incredible, but true.
Maybe there is another difference between English language and what you are using in the Colonies and you are not using 'balk' at all.
The theme was the usuall mixing-up between Balkankreuz und Balkenkreuz. IdFlieg cannot provide anything to solve this Balkankreuz mystery. And as you can see, there are opinions that Balkankreuz has really to do with the Balkans. So I wanted to give some sort of a mnemonic trick.
That's why I wrote 'nearest english' expression. Nearest. Not best.
