Hasselblads current screen with microprisms is the 42215. This screen also has a split in the center.
Could be Maxwell or Brightscreen have what you are after.
They are the only manufacturers besides Hasselblad that provide quality screens.
Forget about the Chinese made screens. These are no good, they are very dark and most important: they are not made according to Hasselblad specification meaning the cameras adjustment for the screen needs to be adapted.
