Neil, Bill made very nice wheels and well ahead of their time. He was anal about perfection and one of the best craftsmen I know. I watched him form, fold and rivet a replacement McLaren F5000 chassis with basic tools. He did the same for a Lola F5000 car back when you could find these chassis reasonably cheap.
Bill made a set of FSV wheels for my Lola formula super vee back in the mid 70's. I lived in Santa Ana at the time.
