If you have the toggle switch, it is a holding magnet selector with
two 92 ohm coils.  Which are usually somewhat rectangular in shape and
covered with greenish material.  The pulling magnet selector has black
cylindrical coils and no toggle switch and is 60ma only.

What probably happened here, since the machine works with the motor
running, is that you were doing your tests when the shaft happened to
be in position where a cam was interfering with the selector armature.
If you turn the motor by hand there will be positions where you can
easily move the selector armature by hand, and others where it is locked
in position.
