I found a previous owner name from about 1983.
Anybody in the Holland, MI area that knows or knew a Russ Jacobs?
Apparently he was a bodyman, and also restored old gas pumps at that time.
Here's the used "By Berger" emblem I found with help from another member here.

Don't text and drive.
Somebody's life may depend on it!
