Solution to the historian's puzzle?

This post is a short update to my recent post on different versions of Düstur

Safa Saracoglu solved at least part of the riddle by pointing out via email that, before Düstur became a series from 1872 onwards, three independent volumes were published under the same title in in 1851, 1863, and 1866. Hence, what I thought of as the first edition of the first volume of the first series of Düstur was indeed the 1863 volume.
