Did this series share any parts? Specifically the balance and hairspring? Seeking cal 330 donor if not.

Some of the calibers share balance parts with some contemporaries (311 with 500 or 355, 440 with 430,435 or 335) but the 330 has no interchangeability. Spares may be available, but a donor movement is likely your best bet.
