When I wanted to fix a leaking petcock on my 700SC (since sold), I could not find that one gasket with the 4 holes anywhere. Like you, Peter, I had asked this group and others, but no one knew an actual source for it. Incidentally though, I had another petcock laying around that I had bought on eBay earlier. Its gasket wasn't an exact fit, but close enough to fix the petcock on the 700SC.
