Phase III super Spark CD boxes

[PxTx]

I've always thought these were the coolest looking aftermarket ignition boxes from back-in-the-day. I've also wondered about their origin. Here are 3 pics form the same magazine in 1969.

Does anyone know what the electrical tape/ sticker is to the right of the Phase III sticker? I don't think the majority of the boxes had this, and I was wondering if it was used to cover up another manufacturer's name. Any other theories?



This pic is in several mags, but I tried to scan it form the new Motion book in hopes it would be a little clearer. Does anyone know what it might say? My pop is speculating it might have the ignition tune data.



This is a pic from earlier on in the magazine.
