i have wondered about the rolleinars for some time, as to whether they were just a rebadge of the lenses mamiya marketed with their own cameras. the lens pictured in the link you provided is identical in appearance to the auto mamiya- sekor sx 135/2.8. the only difference being, as far as i can tell, that the m42 auto mamiya-sekor sx line was not multi-coated (at least, the ones i own do not look like they are).
