I've had a look through the Archive to see what could be found. Results were disappointing I'm afraid. A couple of images of Deke playing it, which of course obscure the top cut-out and, as George says above, nothing of the back. Most of the pictures show the Tele with a Strat neck, during the period when the original was being re-fretted.
For now, the front cover of Iceberg is about the best I could suggest.
Cutting the holes out would probably have been a drill it and join up the drill holes exercise. Deke never struck me as a man who might be handy with a router.
