NumberDummy: Good points, thanks! I do have a Ford of Canada brochure for the 1965 Ford/Mercury Light Duty truck line. There are pictures of the interior dash, but none show a radio of any kind? I signed up with an Antique radio forum and a Philco radio forum, so maybe someone there will know what that code engraved on the side means? I'll carefully take the radio apart to see if there are any other numbers on it. There was a tiny sticker on the bottom, it noted "Union Made"? Not much to go on, but I'll post some more pictures when I get a chance.
