Thanks to a loan from Tom K4NCG, I have now posted scans of this drawing -

You can download from my TCS page at

18Q-3 system drawing (1943)

• Gray JPEG
• Gray PDF
• Black/White PDF
• Original Color Scan PDF

You should be able to get these printed full size at a copy shop like FedEx (maybe Staples can do large size stuff too, I don't know).

And thanks to John K4OZY and his large-format scanner..

Cheers,
