Articles that were verifiably his were the lengthy article on chronology, article on overseers. They are omited or rewriten for Insight.
Though there are some significant alterations to the versions of the Chronology articles in Aid and Insight, there is no evidence that 'those are the bits Franz wrote' (or that the remaining parts are the bits he didn't write). Most of the omissions relate to weak apologetics that raise more questions than they resolve (especially inconvenient after the publication of The Gentile Times Reconsidered), as well as material that is already covered in other articles such as 'Persians', or that was too outdated by the time Insight was written.
