Try contacting Gail Fowler, Curator of the Coast Guard, in Washington, D.C. 
She can tell you if the Coast Guard has any Fresnel Lens that might be
available on loan.

Another possible source of information is Wayne Wheeler, president of the U.S.
Lighthouse Society.

I'm sorry, but I don't have contact information for either Ms. Fowler or Mr.
Wheeler at hand.
