Larry,
Very grateful for the information on Köhnke. This refutes the comment in the Ultra decript summaries regarding Totenkopf/Bienenstock being under the command of a former commander of (F)./123 = another correction for my notes.
Don,
Unfortunately, I cannot comment on that and would need to leave that to one of the guys with more knowledge than I on the subject.
However, what I would say is that there were a number of Bu 181 staffeln raised during the collapse to operate in an anti-tank role using Panzerfaust 100s. e.g. Panzerjagdstaffeln 1, 2 and 3 (some physical and some paper units). I also have noted reference to other Panzerjagdstaffeln in the Air 20/40 summaries but no mention so far of Falke III (I wonder what Falke I and II were and if there was a IV etc). For a short article on the Bu 181 please follow this

Once again many thanks to everyone for the additional information.
