Kelly,
Bill's name comes up quite abit in that nice Dyckia blog.
DyckiaBrazil Forum
I have two of his crosses Dyckia RubySnow and Hechtia Aztec Sun.
Maybe Quail would be interested in starting a Bill Baker hybrid garden.
I will donate two of mine.
There was another Hechtia called Fire Chief...but I can't find it anymore.
