1928
An old AEG Vampyr upright straight suction (no brushroll) - the first vac that was assembly lined in Europe ever (still waiting for its restoration, so many parts missing).
Hey Sam, this avatar pic of yours, does it resemble you or was that just an arbitrary pick? (Sorry to drift off topic).
The Vampyr vac still needs some serious redo and a severe "spa weekend" so forgive me for not having posted pics.
