I'm wondering if Philco was experimenting with the high fidelity controls for their introduction of the 680X for the next model year? That would be a possibility being that the 680 chassis used the same control layout...and they were both high fidelity sets.
The 680X chassis is a much different and much more complex chassis, however. Just a thought...
