  The Kaweco aerometric..., July 17, 2013
By red...
The Kaweco aerometric converter works well, with several squeezes, and being able to easily use bottled ink is a terrific alternative to cartridges.

One caveat: this converter will not fit in certain, early Kaweco Sport fountain pens. If your fountain pen has a nib with the Kaweco logo, and the nib size abbreviation is engraved as a cursive capital letter, the converter will not fit because the converter's metal sleeve will prevent it from seating properly. Some early versions have the nib size as a cursive capital letter on the side of the nib and the words "Germany since 1883" are engraved above the logo. Also, these nibs may not have a breather hole. It appears that the main identifying feature on these earlier pens seems to be that the nib size was always engraved as a cursive letter.

The converter is supposed to fit snugly inside the section and connect with the feed nipple. This is impossible in the earlier versions of the Kaweco Sport because the feed nipple is further down in the section and the aerometric converter cannot be pushed in deep enough to fit properly. An possible alternative converter, without a metal sleeve, for the earlier models, can be found as a mini-piston type converter, like the "Rosetta Mini Fountain Pen Converter" sold on eBay, but I cannot guarantee that converter will fit all versions of the Kaweco Sport.

The aerometric converter sold by JetPens will seat properly and work correctly with later, newer versions of the Kaweco Sport. At this time, I have identified these models as ones with a nib that has the round Kaweco logo and the words "Germany since 1883" engraved above the logo. The nib size abbreviation on newer Kaweco Sport fountain pens is engraved as a manuscript capital letter (like M for medium) and not a cursive letter. Another indicator of the correct pen is that the nib breather hole is somewhat larger on the newer pens. The main identifying feature on the newer model nibs seems to be that the nib size is engraved as a manuscript capital letter. Please note that the design of this pen could change without notice.

The Kaweco Sport is a wonderful, handy little fountain pen and this aerometric converter makes it even handier.

An excellent converter, but please note: Early versions of the Kaweco Sport cannot use this converter.

I forgot to mention, in my other review, that JetPens sells a perfect mini-piston converter that will work in the earlier Kaweco Sport fountain pens (please see my other review for details).

If you have an older Kaweco sport, purchase the Monteverde mini-piston converter sold by JetPens. It fits properly in the older Kaweco Sport pens (including the "Chess" model), and it works like a charm.

Thanks to JetPens for their excellent service!

Was I cautiously optimistic that this converter would work? No - I was downright suspicious. But, not only does it work, it works really well. I holds firmly in place, fills properly, it fits. This adds greatly to the usability of my Al Sport.

I found this converter to be very tiny, awkward and messy. Although it did work and may have been my technique.

I used this converter for only a few days before converting both of my Kaweco Ice Sports into "eye droppers", by pouring the ink directly into the back of the pen and lightly coating the threads with 100% silicone grease. No converter or cartridge needed...and holds 4-5 times the volume of ink. Works like a charm.

I'm ambivalent. I've been waiting for a long time for a converter for these pens. I have an Ice Sport that I've had for over 10 years. This one fits and seats well. Because of its size it's hard to fill, at least for someone with sub-monstrous but above average sized fingers. I don't think I can get it to take as much ink as a cartridge holds even using tweezers to squeeze the bars.

I was looking all over for this converter and missed out the last time the item was back in stock. I finally purchased this item a few weeks ago and was SOOOO glad. Now I can use my favorite bottled inks.
