content: This instrument combines a mechanical pencil and a slide rule. The pencil has a metal body surrounding a black plastic tube, which is pulled out to move the scales. Four white plastic logarithmic scales are glued to the pencil. One pair of scales is divided logarithmically from 1 to 100 (as A and B scales), and the other pair is divided logarithmically from 1 to 10 (as C and D scales).

content: The black plastic tube (underneath one of the A/B scales) is marked: MAKEBA-KOMBINATOR. The black plastic tube surrounds a metal tube and spring, which connect a metal tip and a plastic pusher. A pencil lead is inside the metal tube. A sliding plastic indicator is in a metal frame with a ridged edge for gripping.
