Hi,
Here is a video from Chase Hines (vacman96): it is a 1989 Royal Classic model #9700. If you listen to the motor, you will hear the old six-bladed fan rather than the nine-bladed one. This leads me to believe Royal started using the nine-bladed fan on their product after September of 1990 (serial # begins with "I90").
The old six-bladed fan carried a part of #R-053004. The current nine-bladed fan carries a part of #R-608005.
