I'll keep my eyes open for any interesting materials. You might see if you can find any of the old "Maru Mechanic" issues on eBay. They are packed with technical drawings, probably taken straight out of maintenance manuals. The 3-views are also incredibly detailed. I've got three old ones. I swear I have a profile on the Saijun somewhere...but maybe I just looked at in a shop. I think it was the Koku-fan profile.

For nostalgia sake I also picked up a couple of old model airplane magazines.
