Sorry, I forgot more infos... The bulgarian doc is blank, and I don't have any more about Cuba and Hungary (too scarce I suppose).
There doesn't exist equivalent medals for Romania, Mongolia and Yugoslavia. But in the comprehensive system of GDR medals, there're two other medals (one comes in three classes) dedicated to the border guards.
The hungarian and the polish medals come too in three classes.
