Wanted: This Gear For A VV-V-3

[Dave D]

I am trying to help a 14 year old fix his little Orthophonic phonograph. From his description of the problem it sounded like a broken spring. Once I cleaned it D up, I discovered that this large gear which mates with the bull gear is badly chewed up. Actually, it is the smaller pinion in the center that is chewed up. Can anyone help me find a good one? I have two photos as reference. One shows the motor so you know what I am talking about and the other shows the bad gear.
Thanks!
