I just revamped my history of Baker's Island Lighthouse in Salem, Massachusetts. In the course of doing this, I found a video clip from nearly 20 years ago. It shows the fourth-order Fresnel lens removed from Baker's Island in the 1970s. At the time I shot the video, the lens was on display at the Shore Village Museum in Rockland, Maine. That museum later grew into the Maine Lighthouse Museum on Rockland's waterfront.
The man you hear talking about the lens is Mr. Lighthouse himself, Ken Black. Most New England buffs are very familiar with Ken -- he was a retired Coast Guard officer who rescued many artifacts and built an incredible collection that's now the basis of the Maine Lighthouse Museum. Sorry the quality of the video isn't great. The transfer was done many years ago. I need to dig up these old tapes to do new digital transfers one of these days.
