I don´t think so, because I´ve never seen one of the 25 for 1870/71 awarded knights 1st class of the White Falcon on an authentic medal bar. Beside this I only know one other bar with the absolutely scarce XX years service cross of Saxe-Weimar. Taken additionally the current marked pices of an 1870 Iron Cross 2nd class with Oak Leaves and a Red Eagle Order 4th class with smooth arms in perfect condition, the price ot that medal bar (+ ribbon bar!) wasn´t "insane" at all. In the end for me it was a singular chance and I am sure, that such a combination will not come across again for years. In a price catalogue IMHO it should get a *star* for "fancy price".
And yes, I messed with it 😱
