As the Lighthouse Keeper at Battery Point Lighthouse Crescent City CA, we have a 4th order Fresnel on display. We also have the original lantern that was used in it, Question: It has a tubular wick with a handle on one side and a cup like handle on the opposite side it looks like it could take about a gallon of oil. How was it filled, how was the wick wound up or down?
How long could it burn? These are all the questions being ask with no answers. Can anyone help? Thanks, Frank
