A most interesting webpage about Nagler is Hoyt Stearns' My Dr. Bruno Nagler pressure jet helicopter site, containing rare and never-seen-before photos of the workshops, the test-rigs and some undesignated prototypes.
Most interesting there is a video of the Voljet SX-255 with inflight coverage (very similar to the Model 205 shown above):

As you can see in images one and two below, the Eagle was not just a spinoff of the Phoenix, it simply WAS the Phoenix under a new name. Both ads use the exact same illustration, with only the stars removed on the tail (see images six and seven for the entire original ads).
Third image is a cutaway profile view of the Phoenix.
Fourth image shows a model depicted as an Eagle II, which seems to have a shorter frame than the first model.
Fifth image shows the "demo 1976" Eagle helicopter, obviously prior to the acquisition of the Nagler design, which has nothing in common with it.
Sixth and seventh images are the original Phoenix and Eagle ads.
Thanks Gunship. I did not mention that page before for lack of any information on what Nagler design this is, but of course it deserves some attention.
From Aero, October 1964, the Nagler Vertigyro VG-2, described as a kind of series version of the VG-1, powered by an engine with 220 hp, length 5.46 m, rotor diameter 10.97 , weight 740 kg, speed 240 km/h and a range of 400 km.
