RE: Balsa USA 1/3 Scale Sopwith Pup
Zero my compass was scratch built. I found a solid wooden ball of the right size and hollowed it out with a dremel tool. Then I added the compass it self made from styrene. The outer ring with lettering is also made from styrene I cut to fit. The gimbels are made from dowl rod. The mount is also from styrene. Sorry I don't have any pictures from the side.
