Hi there, I was recently given an Optimus 930 that will need a bit of work. The fount does not appear to hold pressure, and the rubber gasket under the fuel cap appears to be worn. This is a later-style fuel cap with the large "wings". Is there a good U.S. source for replacement gaskets? I have been searching and can't find much. Or....does an O-ring work properly under the fuel cap? The second question: What is a good way to polish the brass parts on this lantern? It is tarnished, dusty and a bit greasy. It would be nice to get some shine back. Thanks! -Cameron
