I guess I have 2 questions. Is this type of filter safe to use and assuming that these are the original filters could they have degraded with age.
I have contacted the Robert White Company in Boston and have gotten pricing on overhauling this sextant and replacing the filters with new polarizers. But would like to have input from the folks on here about this subject.
