Yes, it is a George Thomas design! I understand he did some simpler, commercial units earlier in his career, but I don't know enough to say which brands he designed for. The "Kennet" name rings a bell, but I can't say for sure. For me, the Pillartool is a genius design, and George Thomas was a truly exceptional engineer. I have his book on "Dividing and Graduating" as well. I am looking for his "General Workshop Practice" that he mentioned planning to put out, but I don't know if he ever got to it. But I am in Tucson, Arizona, and info here is pretty sparse. .
