I have some stripped Accutron 214 pillar plates here. One is looking uncommon to me. See photos.
The left is the one of interest. What kind of 214 movement is it? There is no milling for the coil lead retainer plate, but an additional milling and bore above the tuning fork cups. It has no date code and 4 slots near each of the coil form screws to lift the form using a screwdriver.
