Mercedes on here? Couldn't find category. rare 540K in Berlin

I read that the ex-King Ghasi 540K (Erdmann & Rossi) is for sale in Berlin.
I am curious if this is the real car or the twin made to it before the war.
S. Hussein was reported to have stolen it. Some Americans photographed the car during the first wave into Iraq but apparently it got to Germany.
I also heard there was two replicas made by the restorer in Germany who restored it as favor to saddam so maybe the car in Berlin for sale is one of the replicas.
There was a story about it in Car & Driver in 2007
