Found this film , "Weatherbeaten Melody" (directed by Hans Fischerhoesen) via Hans Bacher's blog Animation Treasures (which has since moved to Animation Treasures Version 2 because he ran out of space for posting more images on the first one).
I'm amazed by the level of technical sophistication in the use of multi-plane camera and pseudo 3D effects in this film. Remember , this was in 1942 before computer driven motion control cameras , so all these multi-plane shots are being done with a camera rig controlled by turning gears and sliding peg bars one frame at a time , with multiple layers of cels on glass platens. I have no idea what Hans Fischerhoesen's multiplane camera set-up looked like , but based on these shots Fischerhoesen's studio was doing camera work that was somewhat advanced beyond what the Disney Studio was doing with their Multi-plane camera and what the Fleischer's were doing with their Stereo-Optical process (cels photographed in front of table-top sets for a 3D effect). This clip shows a couple of technically stunning, beautiful scenes from Weatherbeaten Melody. The first is from the opening shot of the movie, then the second excerpt is from when the little bee finds the discarded phonograph in the meadow.

And yes, this film was produced in Nazi controlled Germany, but actually has a subtle anti-Nazi theme. For more on that see the excellent article by William Moritz published on AWN.com based on his longer article "Resistance And Subversion in Animated Films of The Nazi Era: the Case of Hans Fischerkoesen"
Fischerkoesen's films are on YouTube and GoogleVideo. Here's a handy link to a blog with embedded versions of Fischerkoesen's films:

Just for extra fun, here's a link to a clip of Max Fleischer's Stereo-Optical process in action. I love these shots !
