My Aunt gave me my Uncles 1850s vintage sextant.
It all works but it is very hard to read the scales.
Both scales are silver and I cleaned them very lightly with a drop of oil.
The vernier scale (the one on the index swing arm) looks better but the main arc scale is still very light.
It there some way to make the marking on these scales easier to read?
There is also a window for a small piece glass.
The glass is missing.
What is the purpose of the glass?
