With mutt I had a view at the collapsed 7 respective 34 threads.
One then sees the very first E-Mails of a thread and among other
information their subjects.
Via editing I produced two lists with subjects and then searched
each of the 7 in the list with the 34.

Yes.  I understood the commit message of the commit you
referenced in the email I answered to, that now notmuch uses
 Reference: headers to do the threading.  I had a quick view at
the References header in the mbox file and none looked
suspicious.

Ciao, Gregor
