Abstract
A motion picture film spool and spool drive are provided respectively with cooperating drive pin receptacles and drive pin mounting apertures offset from a square spindle receptacle axis on the spool and from a square spindle axis on the spool drive, one receptacle or mounting aperture located radially through a corner of the square spindle of the drive or of the square aperture of the spool, and a second receptacle or mounting aperture on a normal to a side of the square spindle or the square aperture. A drive pin is selectively mounted in either aperture in the spool drive, so that the spool drive may be used with spools with offset drive pin receptacles in either position and the spool may be used with spool drives having offset drive pins in either position, as well as with each other.
