Based on research and an examination of other guitar brands' models from the
  same timeframe (late 60s - early 70s), I have drawn the conclusion that the
  manufacturer of the Jedson semi-hollow/thin archtop was TEISCO -- although in
  the late 60s, Kawai purchased Teisco and continued to manufacturer the guitars.
  Since Jedsons appear to have lived between 1969 and 1973, it is possible that
  Kawai was the actual manufacturer
