As far as I can tell American fiberglass Corp was a division of General Recreation Corporation and the American Fiberglass corp sailboat was run by a man named David Stanton in the early 70's. who also started his own Company in 1976 Now known as American Sails http://www.americansail.com/index.php
it also seems some of these boats were made by a company called Atlantic if Atlantic and American fiberglass are one company I do not know at this time
and the original boat was designed by Philip L Rhodes in 1960
by checking NADA guides found values on Kingfisher from 1971 -1978
I did find one online that is listed as 1968
I would appreciate anyone who can shed some light on these subjects
