This Rumpler is registered in
the first series of German registrations (1919 - January 1920).
Clearly then it did not fly with DLH and the badge on the rudder was
probably painted on
for an air show.. Judging by the aircraft in
the background I would say the photo was taken
in the late 20s or early 30s. Gunther Ott,
from whose collection this rare shot comes, identifies
as a Rumpler C.IV, although it was listed as a C.I in the register.
