Boeing 707-620 Project

[Luca]

Hey,So while looking at unbuilt planes,i stumbled across a line regarding a 707-620 variant,it regards it as a Domestic range-stretched 707-320B,but no matter where i look,i can't find 1 mention of the 707-620 variant that was scrapped

Wondering if maybe some photos of this Never-built 707-620 exist somewhere.

 

[SCAT-15F]

I recall a 22,500 lb thrust version of the JT3D slated for this aircraft (or maybe it was the -820). CFM-56 would have been perfect.

I've looked a number of times to find a 3-view, because the wing changes would be particularly interesting. Presumably, it lurks in Boeing's archives somewhere. All I know of is this picture of the model in Boeing's HQ, which is a generic 707-600.
