Stoker; The Solar Engineering company letters I have make no mention of “Ed and Jeanette Morgan”. The ca. 1977 letters I have state Clyde I. Griffin as Director. And John I. Griffin as both a major company exec AND the General Editor of Andy Ross’s First Edition book
Associate Editor was Mary A. Hanshew.
Something big must have happened around ca. 1981 in the Company as the company address seems to have changed. Maybe 1980’s were Ed & Jeanette ? Maybe Ed was JEMCO ?
