Hi,

I am confuse and I can't determine what real Model-170
is ?,was it aircraft or only a rotor.

Also the Model-213 was V/STOL Tilt/Stowed-Rotor aircraft
project.

Thanks. eBay wasn't cooperating for me when I tried to extract the images.

This is Boeing Vertol's Light Intra-theater Transport (LIT) concept, which MAY have been the same as the Model 170 tilt-wing. I think we already have that image and several more somewhere on this forum.

Just to make my post clearer: the tilt-wing design in your image was variously called a Piasecki or a Vertol depending on the sources. What is certain is that the PH-76 was not a Boeing design at all, but was acquired when Piasecki Helicopters assets were purchased by Boeing (Piasecki then went on to create a new company).
It was a projected development of the Vertol V.76C prototype (the Army/Navy, then NASA VZ-2).
An unbuilt flying test-bed for it was designated PH-76J, as evidenced in a military report (see second image).
