Opening of a short-lived Dresden - Magdeburg - Hamburg floatplane service along the Elbe. A rather grand terminal building was erected here which still stands. The nearest F 13 can be identified as D-433, which was registered to the Junkers-affiliated Sächsische Luftverkehrs AG with the name Baumlaufer. Based on another photo, the other machine appears to be D-272 Silbermöwe, listed as one of the two regular F 13s on this service, together with D-583 Wildente.

D-433 was used by Westflug GmbH from Bad Oeynhausen during 1926. In the autumn it made proving flights for a planned Cologne - Duisburg - Rotterdam service along the Rhine. This service was carried out by Lufthansa during the 1927 summer season. The same aircraft was photographed with Lufthansa markings at this same spot near the Rheinlust restaurant in Duisburg - Wanheim. However, D-433 went to Austria early in 1927.
