I recently purchased this barometer and was wondering if people could help me with any details.
Firstly, the front, clear cover: I expected this would be glass, but it is actually a plastic (and doesn't look recent); is this correct?
As well, I was a bit surprised to see how cloudy it is, and that it is turning a definite green colour. Normally I see old, clear plastic go cloudy but more of a yellow tone. The photo does not capture just how green/blue the plastic is! The housing of the barometer is a bit rough, so I'm sure it wasn't stored well for all these years, but the face is in very nice shape.
Note: the needle has since been adjusted to a more correct 1009 mb, and it is varying with our local weather quite well, although a bit more "exaggerated" than our local weather station suggests . Any advice on maintenance that should be undertaken, or not, would also be appreciated!
