Gray portholes
Gray Co. of Tampa is still in business. It is a division of Pompanette, Inc. under its Bomar division. Their Phone # is (813)885-2182 and their address is 7712 Cherri Court, Tampa, FL 33634. call them and find out if the screens are available. I recently purchased dogs and rubber seals for all my ports. I ordered through Bomar and when I received the order in two days I was surprised until I found their warehouse was in my backyard. Not cheap but good.
