Still going through my email backlog, here we have some photos that Bruce from Radio Noir sent me way back in December last year. They are of a portable harmonium that dates back to WW2, and is still in use.
I believe that this is an Apfelregal, an early portable reed organ. The globular resonators give a more mellow tone than the raw reeds of simpler regals. That was reconstructed from ancient models for Vienna's Technical Museum.
