I'm trying to find out what car this radiator cap came from. It was found at my great grandfathers house. He had a car dealership that sold Dot, Veile, and Marmon. I gave the cap to a friend, and he put it on ebay without asking me. The auction will be canceled so that I can get it back. I can take some better pictures on Monday when I have it. The ebay item number is 110106782761 The 3 pictures there should give you some idea of what this is. Any help would be appreciated. Thanks
