Is that one with pot metal pulleys? Early Sparton pot metal pulleys may not be usable. They warp and crack over time.
Atwater Kent used similar (brass) pulleys in their Model 37, 38, 40, 42, 44 and several other radios. Might also check with a hardware store. Pulleys have to be all the same but not necessarily the exact size as originals.

:Does anyone out there know where I can find a tuning drive assembly for a Sparton 6-15?
Thanks Norm, I'll look into your suggestions.
