General Electric 612 missing dial part

[Matthew L]

i just came across a General Electric 612 radio and was wondering where i could find a this dial/knob thing that goes on top of this radio , or find something that could work and be made as a replacement . seems like no other radio uses this type of dial so i know it wont be easy to find one . i did not find a actual picture of a black one like mine other than this photofact one ,but i did find a picture of a red one to show what it should look like .
