Pre G1 Whirl?

So, yesterday I bought Rodimus prime and what I thought was G1 whirl for $1.50.
Anyhoo, I looked for the Copyrights on Whirl, knowing that it is a borrowed mold, only to find the copyrights are:
On one foot: Bandai, 1984. Also stamped with Bandai logo
On the other foot: Ashi Production 1984.
Is this the Pre-G1 or were copyrights unchanged for G1?
