Recently I purchased two Ritchie BN-202 compasses off Ebay. They looked just as bad in the shipping box as they did on Ebay. Domes had spider cracks, bezels were oxidized and the LED bracket was broke on one. I have rebuilt one. The rebuilding consist of new dome, bellows, fluid and LED bracket. A little Mcquires magic plastic goop on the bezel makes the bezel nice and black. There is a tiny little bubble in the fluid, its about
the size of the tip of a sharp #2 lead pencil. I have tried for several days to get that little sucker out and I have failed.
So the question is this, how does one get that little bubble out?
