Optical cross section for 90-180 Zoom?

Being an optics nut and already having the other cross sections for the rest of the Pentax 67 lenses, I was curious if someone has ever seen what the 90-180 zoom cross section looks like? I'm guessing it is similar to their zooms for their 35mm cameras.

I don't have that cross section, but I'd love to see the design of the 800/6.7 EDIF. If you have that and wouldn't mind sharing send me a PM.
