Turn Coordinator moisture under glass

Condensation formed inside
my turn coordinator yesterday. Is this a cause of concern? Repair? Replace? Installed in a 1949 Cessna 140A.

It is a humidity thing and will resolve itself the next time you get an extended period of low humidity weather. I had several steam gauges on my airplane that used to do that. Now I have digital gauges, which don't have glass faces, but probably have just as much condensation inside.

Personally, I wouldn't replace it unless it failed.
