Stella Wien - Model 306E - Desider Stern, Vienna (Austria) - Part 2

The model 306E, during its very limited commercial life, was sold by the trademarked name "Piccolo", as this back of leaflet testifies:

The name "Piccolo" was also used to sell the Model 305E (picture here or here).

Both remaining model don't make mention of the "Piccolo" trademark.

Both still show with pride the Stella plaque, although on the machine of Dr. Ursula Becker, it looks slightly different.
