Pre Rub
The 1984 releases of the Autobots and Decepticons (as opposed to their 1985 releases) are referred to as Pre Rub versions because the toys do not have Rub Signs or the indents retooled into some of the toys for them. Another distinguishing characteristic of Pre Rub Transformers is that the trademark symbol above the final 'S' in the Transformers logo is a ™ instead of an ®, indicating that Hasbro had not yet registered the trademark at the time these toys were made.
The earliest versions of Autobot cars and Decepticon jets (those shipped in cases marked "March 1984") were No Gray Border Pre Rubs, referred to as such because the gray border that normally goes between the box art and the window is missing. Also, some of the text on the front of the box is black instead of white. Some No Gray Border Decepticon jets contain sanded Diaclone wings instead of the normal shortened Transformers wings.
