I have a query on filling systems. I am looking to buy a Visconti double reservoir filling system at some point. I am not sure but it looks like Aurora 88 has some thing similar: It says 'Filling Mechanism: Piston with “Emergency Reserve”' here --- http://fpgeeks.com/2012/02/aurora-88-large-fountain-pen-the-awesome-review/. Could anyone enlighten me on the difference between them? Thanks.

The systems are different.

 

Visconti's system is basically a plunger filler with a wrinkle. Visconti's double-reservoir pens actually have two reservoirs divided by a wall with a hole and the movement of the ink between them is controlled by a cut-off valve. You open the cut-off valve by unscrewing and pulling out the plunger-knob partially; push the plunger back down (and screw in the knob) and you close the valve. The smaller reservoir is nearest the nib (probably holds about a cartridge or so), the larger reservoir is further back. When the smaller reservoir runs out of ink, you need to open the cut-valve, i.e. unscrew the knob and pull out the plunger partially, so the ink the large reservoir fills the smaller one. You can then close the cut-off value by screwing the knob closed. That said, those who like not to have to fuss during long writing sessions will just leave the knob partially out, so the ink flow between the reservoirs is constant -- like one big single reservoir. If you're into rough bumpy travels, or radical changes in air pressure, e.g. airplanes, then the claim to fame of the Visconti system is: you can move all think into the bigger reservoir and close the shut-off valve. Air expansion in the smaller reservoir is kept in check and you won't see burping of ink.

 

Aurora's "magic reserve" in the big 88 and Optimas is different. For one, you only have a single reservoir piston filler. When the ink has run out in the single reservoir, given the special shape of the piston seal (and probably nib unit as well) you can unscrew the piston knob -- as you would to fill the pen -- and that will force a wee bit more ink into the feed so you can write a bit more. It's not a lot, but if you need to write a few more lines it's enough to get the job done in an "emergency".

The neatest "reserve" system I remember is the Parker cartridge. The shape was such that a small amount of ink, enough for just a few pages, was held at the back end of the cartridge. If you ran out of ink you just unscrewed the pen, flicked the end of the cartridge enough to break the surface tension and went on writing.

Does original semi-hooded aurora 88 of early 1950s have same piston mechanism or is it more basic?

I do not know, I don't own a vintage Aurora magic reserve. Send a PM a sanpei (Paolo), he'd most likely know.

Thanks for the suggestion. Just for the completion of this thread, I am pasting what sanpei (Paolo) told me over PM: "pistons are lot different but "riserva magica" system works in similar way,

a bit of ink is stored in a small room, closed when piston seal is retired, room is opned when piston is fully extended."

      I have the Sailor Naginata and some fancy blade nibs coming after 2022 by a number of new workshop from China.  With all my respect, IMHO, they are all (bleep) in doing chinese characters.  Go use a bush, or at least a bush pen.

      It is the reason why I'm so keen on the idea of a personal library — of pens, nibs, inks, paper products, etc. — and spent so much money, as well as time and effort, to “build” it for myself (because I can't simply remember everything, especially as I'm getting older fast) and my wife, so that we can “know”; and, instead of just disposing of what displeased us, or even just not good enough to be “given the time of day” against competition from >500 other pens and >500 other inks for our at

      Agreed.  And I think it’s good to be aware of this early on and think about at the point of buying rather than rationalizing a purchase..

      Alas, one cannot know “good” without some idea of “bad” against which to contrast; and, as one of my former bosses (back when I was in my twenties) used to say, “on the scale of good to bad…”, it's a spectrum, not a dichotomy. Whereas subjectively acceptable (or tolerable) and unacceptable may well be a dichotomy to someone, and finding whether the threshold or cusp between them lies takes experiencing many degrees of less-than-ideal, especially if the decision is somehow influenced by factors o

      I got my first real fountain pen on my 60th birthday and many hundreds of pens later I’ve often thought of what I should’ve known in the beginning. I have many pens, the majority of which have some objectionable feature. If they are too delicate, or can’t be posted, or they are too precious to face losing , still they are users, but only in very limited environments..  I have a big disliking for pens that have the cap jump into the air and fly off. I object to Pens that dry out, or leave blobs o
