Vintage Snowmobile Fan Wheel Magneto Ring Polaris #3003046 Hirth 21.12/2

This listing is for a vintage Hirth motor fan and flywheel or magneto ring (already installed) that came in a Polaris parts inventory that I purchased. This is a used part in good condition. The Hirth number on this is 21.12/2 and the Polaris part number on this is 3003046.

Looked this up in my old parts book but could not come up with an application for either the Hirth or Polaris part numbers.
