Paul- I too would recommend the US Lighthouse Society. Their address is: 244 Kearny Street, 5th floor, San Francisco, CA 94108. Their phone number is: 415-362-7255 As far as non-glass Fresnel lenses, I just came across an ad for a company that makes Acrylic Optics. Apparently they can be custom made for whatever your needs. The contact for that company is a man by the name of Roger (no last name given). You can reach him at: 863-688-9355 in the evenings. Mailing address is: 1720 King Ave. Lakeland, FL 33803 Hope this helps!
