All, Today I'm looking for one or two Wilcox Crittenden, cast bronze Clamshell vents, 1 1/2" X 1 1/2". These are a triangular in shape and look just like their more modern stainless or chrome plated brass replacements. I need four of them for a project on the boat and to date have only managed to locate three of them and one of them isn't perfect. If anyone of you has one or knows where I can find one, I'd appreciate hearing from you at glynjudson@roadrunner.com or 310.453.1892. Thanks, Glyn Judson, E31 hull #55, Marina del Rey, CA
