I believe the Mystical I have was made in the early to mid 1980's It was one of the few modern "D" shaped or Deflex-Reflex bows. At first he was using black locust, osage, and red elm laminations, under clear glass and shedua risers. Dan Bertalan talked with 29 different traditional bowyers before he published the first ed. of Traditional Bowyers of America in 1989. A second edition followed, as many bowyers faded away and new ones were building bows. I think Felix is correct, as Dick gradually started using bamboo core material and different riser wood when the Vision was introduced and then the Purist.
