You are looking at a revolution in retro writing technology.
Those who know antique typewriters will recognize this as a typewheel for a Blickensderfer ("Blick"), invented by George C. Blickensderfer and made in Stamford, Connecticut. This design was made in several models from 1894 to about 1919. (See the details on The Typewriter Database). It features interchangeable typewheels, a three-bank keyboard (usually arranged in the "Scientific" layout with the most common letters on the bottom row), and inking by roller.
The design was briefly revived by Remington as the Rem-Blick (aka Baby Rem), mostly manufactured in 1928. But for nearly a century, Blicks have been "obsolete" collectors' items and curiosities.
Here are some Blicks I've had in my collection over the years.

no. 6 (aluminum, QWERTY)
no. 7 (English DHIATENSOR "Scientific" keyboard)

Blicks are very clever, but also relatively slow and tiring compared to a typebar typewriter. If only it were easy to find a Blick Electric, a 1902 model (available in a few variants) that anticipated the IBM Selectric! But these machines are extremely rare.
But let's get back to that revolution in retro writing technology:

This is a brand new, made in 2023, interchangeable type element for Blicks. Not only that, but it is equipped with a typeface that was never available for Blicks before: Steile Zierschrift, a decorative type, as pictured here in the 1928 Ransmayer-Rodrian (RaRo) catalogue.
And here's a new typewheel that features an extremely rare italic Remington typeface designed by the famous
Frederic Goudy. (This one has been used, so there's ink on it.)
They even come in their own neat containers with screw-on tops.
But do they really work?
The new typewheels use the font design skills of Brent Carter and the 3D printing wizardry of Leonard Chau. This is the most precise 3D printing I've personally seen — there's no "pixelation" on these small, fine shapes. They're available in several more typefaces, and either in the Blick DHIATENSOR layout or in QWERTY. (QWERTY seems most likely to be found on the aluminum model 6.)
Here are some wheels getting cured after 3D printing. Yes, you see script and Vogue!
Maybe your Blick needs a little attention before it's ready to type. Do you need ink rollers? Buy a box of
gun cleaning felts (7mm) and ink them with
Bates Numbering Machine ink. Are your feed rollers flat? Recover them with automotive tubing or heat shrink tubing.
