Re: Compass Fluid, what to use?
I spoke to a local compass repair shop. As they do not usually sell that stuff but use it for repairs, they directed me to a local art store which is selling Stevenson odorless mineral spirit which is paraffin based and Ritchie are recommending to use it as an alternative to Isopar L which they sell. They have used the same stuff in their compasses from 1950 to 2000. I got a gallon for $30.
