What can be said....another interesting selection.

http://cgi.ebay.de/ws/eBayISAPI.dll?...tem=6216076566 is of the emblem of Verbindungstaffel 65 see same book p269. I seem to remember a very similar photo being offered some time ago.
http://cgi.ebay.de/ws/eBayISAPI.dll?...tem=6216357022 is of the emblem of FFS A/B 121 according to Ketley/Rolfe entry no 715. The town of Straubing this refers to the town where the unit was formed at and based for some time. Is the plane a Klemm?
