Thanks Doug.
Great Challenge.
I discovered that D-1140 later became D-OMUZ but could find no photograph of the aircraft in it's new marking. On the Wikipedia there was a statement that says:-
Deutsche Lufthansa AG - In 1937 confiscates three copies incorporated into its fleet
It would be well worth putting your photograph on Wikipedia under the L.72 heading.
Here is the next one, a bit grainy I am afraid.
