First daisy-wheel typewriter, 1889 has just added this lovely 1889
Victor index typewriter:

This was the first typewriter to use a daisy wheel, which would be a common design feature on 1980s typewriters. The daisy wheel is made of thin brass, cut with narrow radial fingers, one for each character. At the end of each finger is an embossed rubber character.

To operate the Victor one puts the tip of ones index finger in the little cup at the end of the pointer, then swings the pointer up to a full 180 degrees to select the characters. The pointer is connected by a gear to the central vertical wheel that holds the daisy wheel. As the pointer swings, the daisy wheel rotates into position. A spring-loaded hammer then pushes the brass finger in the daisy wheel against the paper.
