It appears he began is mouthpiece business by purchasing blanks that already existed before being able to make or source his own custom designs. It sounds a lot like what Jody Espina did in creating Jody Jazz. Jody's earliest mouthpieces were customized Runyons before he could afford to make his own designs from scratch.
The mouthpieces themselves appear to be just cheap plastic blanks that Lakey worked on. There doesn't seem to be anything particularly special about them and there are a couple for sale on Reverb as well as one Sax Alley is selling for $30.
