Landing Compass Fluid
Help Please.
I have just purchased a landing compass ( you know the type-wooden box-prism for sighting-hole in the bottom for tripod.)
It has a medium size bubble in the fluid.
Question:- what fluid does it use and where can I get some.
I have checked and I think it is some kind of spirit but my sense of smell is not very good as I am an old GIT and need some help.
Regards
