M92 Beretta magazine motor - what model?

Trying to find what model of coreless DC motor the M92 magazine uses. Does anybody know? The 612 and 615 DC motor models look very very similar but lack the little spiral that interacts with the gears.

You move that gear to the new motor.

Thanks! Seems kind of obvious now i think about it, it’s apart of the gear setup rather than the motor. I will go ahead with the DC 612 and see if i can successfully fix my own M92 mag. Seems simple enough!
