I seem to remember finding that site many times in Google searches in the last few months and it always being down. I could be wrong.
Dan, I'm sure you are right. My thought was mere speculation based on the size of the optic, which is of course specious at best.
Now giving it some more thought, the obvious conclusion is an SA design. If you take a 90mm f/8 lens with a 216mm IC (Schneider SA, and the Fujinon 90/8 too) and scale it up 3.33x, you get a 300mm f/8 with a 720mm IC. Perfect. Who knows why it is actually f/9.
