John,

You and I met one of the folks involved in building new lenses when we were at St. Augustine last November for the lighthouse conference. (Actually, a year ago this week...) Anyway, Gary Knappenberger of Enberg Mold & Tool Castings (Tampa area if I remember) said they did a lot of the custom metal work for International Chimney projects. He said they could make a lens, but we didn't talk $$. I believe they are the ones who made the replicas of the old brass lightkeepers tooks for St. Augustine.
