All, I just got a lovely pair of vintage WIlcox Crittenden bronze tank vents, the beefy ones that pass through the hull with a large nut on the back to hold them secure and I'm soliciting suggestions as to what to use in them to prevent bugs and such form entering the tank through them. They were originally fitted with bronze screen but they're gone. If this were a perfect world, I'd find some old bronze bug screen from an opening port light or similar (anyone have 4 square inches they can spare?) but I don't have anything like that. Ideas as to alternatives anyone? Thanks in advance, Glyn Judson, E31 hull #55, Marina del Rey, CA
