Yes - the Albatros L72 with Mel being first and taking control.
I found this picture, a private Agfa photo with a postcard back, at an antiques show and invested a small sum in it as a research item - and it took me even longer to crack it. That was even with the benefit of having the full picture with the fin-less tail unit with the horizontal surfaces forward and having recognised the building top right as what would have been the then new terminal at Hamburg Fuhlsbuttel.
Like all of you, the other pictures I have found are of the original newspaper-carrier version with fewer windows but the picture ties in with all three produced having ended up with Hamburger Luftverkehr Gmbh in the early thirties. ( John Stroud - European Transport Aircraft since 1910). The tail markings and flag are not Hitler era.
I hope they enjoyed their flight in ignorance of what was to come, for Hamburg especially.
