The port lights in our 1983 President look like yours. They were made by PYI which was bought by Bomar and relabeled, I think, as their "Gray" line. You can still get some of the parts but not the entire port light. When mine need replacing I will be going with the New Found Metals port lights. I have seen several of them in Boats here, including another President, and I like the way they look and the quality of construction.
