look what I have found!
It seems that there is no real connection between Vorwerk, Regina, AEG and other stick vac brands, but I could find out that the name was "Gustav Brachhausen" (probably the English pronounciation BraKhauen might have turned it into BraThausen accidentially, think of speaking on bad phone lines).
Once you have the name right, you get flooded with information.
The major links for you:
1--University of Leipzig on the "Brachhausen & Rießner" company in Germany. Those made disc operated music boxes, the type where small cogs on a rotating disc or roller snag metal rods. (The lullaby pling-plong tunes, you know them all)

1b--Search youtube for these old instruments in operation and enjoy.
2--Some private radio museum on the "Polyphon" company, their new name. They also featured large units with exchangeable discs:

And finally a pic of my AEG stick vac disassembled, look how similar the fan, the annular spiral path and the oval upwards chute are!
Funny: Music apparatus seems to get quite numerous people hooked to vacs and funny how similar ideas can come up in different heads on different spots of this globe.
