I started hunting one up for you last night, I'v got some pages from the book of word on the S9. I had to make some of the parts for a rebuild. The balls on the governor are ball bearings , annealed and drilled, with the arms riveted in place. The governor works and will hold 400 rpm on air from twenty psi to sixty psi on a light load.
