Beautiful study of what looks to be a rather pristine Dornier Do 23 SD+VD. The aircraft is equipped with four-blade wooden airscrews, and it is camouflaged entirely in grey. Moreover, this Do 23 appears well prepared for any adverse weather events: the cockpit and the forward observation position (accessible from the cockpit, by means of a passage way underneath the instrument panel) are protected by canvas covers, and it is tied to the ground with various ropes at the wing and tail wheel.
Exact date and location unfortunately currently unknown to me. (German Aviation 1919-1945 collection)
