Next message: George Huxtable: "Re: Navigating Around Hills and Dips in the Ocean"
Yesterday I opened up (probably for the first time since abt 1945 ) my bubble sextant which I bought many years ago. and much to my surprise, it seems to work at least for sunsights.
I found the manual for it and the thread about it on this list, but would like to do whatever maintenance/servicing is needed after 50 + years.
I guess the most vulnerable critical component is the bubble diaphram - can SKS tell me how I get to it, what precautions are necessary and where I can get a spare/replacement?
Can anyone help me please?
TIA
