Murray Tooth Grille- not sure what model

buying this from a friend. He painted it yellow and it was red before that but we believe the original color was a gold like my old Fire Drag-on. This has plastic wheels on it that i thought were put on, but have since seen like five of these with the big wheels same as these. BUT none have the motor- the Fire Drag-on has the motor but steel wheels. Any info on this? want to restore but not sure what it is...i will sand it down when i get it and see if there are decals hidden somewhere.
