Eberhard Faber produced this No. 5 three-piece mechanical pencil set. It was made in America (as marked). Circa 1940s. The body sections of the two pieces represent black, green, red, and blue lead colors. The extra leads tube features erasures on both ends and a middle divider to separate the black/green from the red/blue pencils. The pencils are 5 3/8 inches long.

Mottled hard rubber is a blend of black hard rubber and red hard rubber. I'm showing two examples of this material in combo mechanical pencil with dip pen. The little one is marked Day; one of the early makers of hard rubber writing instruments. The larger piece is unmarked (possibly Day also). These two were produced as early as the 1850s into the mid-1880s. Thank you Sam and Frank!
