But here I want to show you an odd feature of the Duocart: the sound to alert the user that the ink is near to ending. The device is very simple: a small ball hanging from the bottom tassel inside the barrel. If you have both cartridges fitted, the ball cannot move, but if only one cartridge is in, while you write the ball swings, uttering a tick-tock.
A nice invention complementary to the idea of the double cartridge. In my opinion it was introduced since the Duocart mainly was a school pen and the device was an help to avoid the end of ink during a lesson. But the entire design of Duocart is easy: the oversized barrel to underline the 2 cartridges, the difference of colour between section and barrel and the addiction of this ironic alarm for forgetful schoolboys…
I do not know who is the designer of Aurora Duocart. Some writers of history of Italian fountain pens assert the author is Albe Steiner, a designer working in Italy in that period; he certainly was a graphics and design consultant for Aurora in '50s and 60s, but I could not find in his biography a reference to Duocart invention (only packaging and advertising, as he did for Aurora 88 too). Indeed Albe Steiner was the designer of the Aurora Sele pens line. In this link you can see some of the interesting works of Steiner for Aurora.
Duocart seems to me a variation of Aurora 88: the exact name is "Aurora 88 Duocart", they are similar in shape, the clip is the same (also if a little shorter) of 88 and so the nib and section: probably it was the result of a collaboration among Aurora, Nizzoli, Steiner…??….. I need the help of Aurora experts. Saluti a tutti, Giuseppe
