Sorry but my newspaper site access is currently down so hopefully others here can give it a whirl there for you.
Online info indicates Courtesy Oldsmobile's owner's name was Sam Shovlain so worth Googling for more info also Shovlain Olds in Melbourne Fl. was probably connected somehow too.
Best of luck w/ your quest also love to see any pics of your W31 Post car!
