My 80 literature gives a pic of a plant with a Glastron Carlson sign in front and all Carlson boats with an address of Austin, TX. My 89 Glastron book which has a pic of a 89 16css gives three plants: New Braunfels, TX Fair Bluff, NC and Barcelona, Spain. From Wikipedia: Glastron is a boat manufacturing company and was one of the first manufacturers of fiberglass boats. Founded in Texas by Bob Hammond in 1956, the company was sold to Genmar Holdings in the 1990s and manufacturing was moved to Minnesota. Then in 2010 they moved from Minnesota to Cadillac,MI. You and Doug might be able to get together and make a Frankinboat.
