Thanks. Chuck (or Charles) Lewis was the name. And the name of his Gobo projector was "Adapt-A-Spot". I Googled that and found one that was sold on eBay back in February. You can still see the photo of the kit there:

I searched around to see if anyone else was selling them or had a PDF of the instructions, but didn't find anything. Also it was not mentioned on Charles Lewis's website.
Cheers,
