Am working on a gas gauge that looks quite different than most. It has a single arm coming off of the side, instead of the wire coming down from between two pivot points. Is this a early 1928? It has the magnified lense, oval shaped. It was frozen tight, with carb cleaner and penetrating oil, I was abe to free it up nicely. This is the only one I have seen this way. I have worked on dozens of these. Jon
