The 12L are certainly DIN as this is the standard in Egypt. But there are always enough adapters for those without own.

You are correct all tanks were DIN but they provided the adapters if needed…I remember clearly that the 15L tanks are DIN. Adapters are provided to convert to yoke. I am not certain if the 12L tanks are DIN. Maybe @Rafael Moreira or @Opa-TX can recall.
