The name Petroczy-Karman-Zurovec PKZ-2 was made up after WW1. During WW1 the machine(s) were known as SFF (Schraubenfesselflieger) in an electric motor version (PKZ-1) and a benzine motor version (PKZ 2).
  On this unique picture (in small size for this quiz) taken on one of the testflights on may 17th till may 21st 1918, you see the PKZ-2 in its second version. Clearly visible is the observer cage mounted above the two counter-rotating propellors. Power was provided in this version by three slightly more powerful Oberursel UR 1 (copies of Le Rhone 110 hp). The original version was powered by three Oberursel U2 (copy of the Gnome 100 hp).
  The designer Wilhelm Zurovec [1883-1935] called them in an article Beute Le Rhone. They engines were of dubious quality, which in the end resulted in a fatal crash on june 10th, 1918.
  On this picture you cannot see the lines (Fessel) which captured the machine to the ground and made it stable sothat it could go up and down vertically.
  Interestingly the Zurovec family donated 9 (nine !) Le Rhone rotation engines in 1938 to the National Technical Museum (Narodni technicke muzeum) in Prague.
