Thats one neat looking set Bob, the styling is very much like some of our NZ native built TV's
Looking at the top dual concentric knob thats not missing, I recognized it straight away as it looks to be identical to the knobs used on some Philips b/w sets made in NZ. Heres the link to a Philips TV on my site showing the same controls -

Hope you can find a CRT for the GE, its worth saving I reckon
