I don't know if anyone really cares, but: The "Zsuzsi" writing is Hungarian (which is my native tongue, even though I moved to the US as a little kid), which means "Susie" but the rest of the writings on it are German, which I do not speak but I do know a lot of words and "Nutzlast" means "Payload" and I think "Leergew" is curb weight? So...I'd assume that, even though this doesn't look like a military bug, I think it was used to move between the two countries...which is pretty cool.
