Mystery Badge

Does anyone know the Manufacturer who used a round badge with an Indian head in the center with a capital S under it? I found it and have no idea as to what car it goes to, if it even goes to a car. And help will be appreciated.

Thanks

Nothing rings a bell.
A picture would be really nice though.
Indian head symbols were commonly used by Pontiac from the '20's to the early '50's, but no symbol with an 'S' comes to mind.
