I came across an article in Model Airplane News (Sept 1987). They had a "Float Flyer's Buyer's Guide". In the article they showed a airplane that is similar to yours except that the tip floats appear to be different. It's a glass fuselage and was made by Tiger Fiberglass and Marine. It's called a "Super Seamaster 60" and was designed by Ken Willard. It has a fiberglass and foam hull. Unfortunately there are no other specs of the plane. There is a small picture but I don't think that it will scan very well.

Good Luck!
