unusual and very very rare, maybe one of the must rare pens of the world.

I've never seen anything like that! Can you provide a little information about it?

[labeo]

in 1932 when the Zerollo was introduced, fountain pens on the market featured everything form lever fillers, various piston systems, several crescent fillers, all made as improvements and simplification to the older eyedropper method, often messy and inconvenient.

The Zerollo Two Pen was created by a Genoese pen maker Dante Zerollo, who obtained British Patent # 397736, and was granted August 31, 933. The inventors were listed as Mirko Chelazzi and Dino Frulli, who were likely employees of Dante Zerollo. The Two Pen appears at first inspection similar to a conventional safety pen with retracting nibs. In this case, the barrel contains two complete fountain pens, each contained in a thin tube with it's own ink sac, pressure bar, feed and nib.

 

Filling this pen required the user to absolutely read the instructions, as it was unlike any other pen ever introduced. First, the cap was removed which contained a short metal rod. This rod is used as a "match filler" to insert the rod into a small hole in the side of the barrel to apply pressure to the pressure bar and the ink sac for filling. The interior of the barrel contains twin spiral grooves for the purpose of propelling either of the two pens contained. A right hand twist action of the end cap would propel one pen, while retracting the other. A left hand twisting would reverse the action.

 

Zerollo Twin Pens were made not only in hard rubber material, colored celluloid, black celluloid, gold overlay.

 

Zerollo licensed his products to John Dunhill, and also to Unic of France who manufactured pens under the brand name Duo-Colour.

A few other Italian manufacturers made twin-nibbed pens, such as Itala, Colorado, and Diana. Duplex, an American company made an inexpensive similar fountain pen also.

A really interesting pen which made me do some digging:

Yes it's true and also it's one of the most complex pen of the story

[tractionavant]

Nice !! a fountain pen equivalent of the 3/4 in one coloured ball pens that are usually seen

[wykpenguin]

I really can't stop myself from drooling over this.

Quite a fascinating pen, for sure!

 

Labeo, in the interest of protecting original authorship, you should probably cite the original author of that bit of information (Len Provisor).

Hello iam from Spain so excuseme if mi english its not good, i have this pen, is the due colori zerollos, if you want pictures i can post some, its in expectacular condition, mi grandfather give it to me, he bought it in Italy Genova i think in the 1940`s thanks to all.

[eckiethump]

Could this possibly be moved to the repair section? so far I have only made contact with one person who has admitted to successfully repairing these pens. The one I have is in near mint condition, other than the internal mechanism being inoperable.

TIA
