So about those Lady Sheaffers...
This is a model IX, Red Balicon. (Nobody knows why it's called "Balicon", so if any of you folks know what that means, please tell me!) I love the contrast between the glossy gold and the red engraved lines. I'm also super pleased to have the box it came in.
These two are both Paisleys, models IV (black) and VI (periwinkle). The nibs are silver-palladium Triumph nibs. The engraving really does give the impression of fabric, and has a nice texture in the hand.
These three are from the later Lady Sheaffer line in the 1970s. From left to right: 632, 921, and 925. (Collectors call them Tulle, Chevron/Flammé, and Barleycorn.) The nibs on these are called Stylpoint and are 14k gold.
The left one is mesmerizing when you turn it in your hands. The other two are almost gaudy they're so bright. Definitely eye-catching pens!
Also I gotta show you this box, the one the Balicon came in. Have you ever seen something more Mid-Century Modern in your life? The ivory plastic, the pebbly texture, the gently curved lines. The way it sort of floats off the table, and the inset section at the front. And like a brooch, a tiny golden symbol in the shape of Sheaffer's signature inlaid nib. Some designer spent ages on this thing and it shows. I love it.
If you like small, slim fountain pens, definitely look up the Lady Sheaffer. For some reason they're not heavily collected, so folks aren't driving up the price. They're cartridge pens so there's no mechanism that needs servicing, and Sheaffer still makes the cartridges.
Unless you like your pens plain and understated, in which case I can't help you. Every model they made is jewelry!
