Fresnel lenses are very hard to come by.  The U.S. Coast Guard will on occasion lend one on long term loan.  Quite often, when the switch was made to modern lighting the lens was destroyed.  All we were ever able to obtain at the last place I worked was one side of a 4th order lens that had been found in Door County, Wisconsin.

Does anyone have (or have a possible source for) a
large Fresnel Lens of the type used in Lighthouses?

This could be a glass original or a reasonable facsimile.
