#10 - Navesink

Clues -

I thought this was going to be easy. Is it a challenge?
Navesink is part of the NJ Lighthouse Challenge

Maybe they used Retsyn to build this one.

The start of the end for Winslow Lewis.
Fresnel lenses replaced Lewis' argand lamps. Navesink was the first lighthouse in the US to be fitted with a Fresnel lens.
