I can't tell you for certain about the "standard" grille but can tell you the deluxe grille halves have a date at the very bottom. It's small, almost undetectable to the naked eye, but it's there. Perhaps that was done on the "standard" grille as well.
Also, you won't find 'Drake' cast on it. I'm pretty sure he was not a supllier to Ford back in the day even though he states often enough "exact copy, blah, blah, blah..."
