Has anybody got lens diagrams for Chinon or Yashinon lenses? It would be good to compare.

The official Mamiya diagram of the standard lens designs shows a curved rear element, although it is flat like in all Tomioka versions. Other members have seen chrome MS 1.4 lenses with a curved rear element, though.

It would be good to compare these designs with the corresponding Yashinon lenses, especially the DS-M 1.4 / 50mm (yes, 50mm not 55mm).
