I'm not quite sure what you are asking, but if you need to know how many parts are in a complete Rolleinar kit... Older ones were a 3-piece set - two rolleinar lenses and a rolleparkeil parallel correction; new ones were two piece - one rolleinar lens and the Rolleiparkeil had the corrective lens in the same housing as the parallex correction prism.
I've learned that the new ones can be distingushed by the inscription on the thick taking lens add-on. It reads Heidosmat-Rolleinar rather than Rolleiparkeil.
