Art 1606 Pump compass

First Pump compass from 1969, to draw very small circles with technical pens.

Perfectly balanced because the center of gravity is on the central axis
enabling drawing of smallest circle down to 0.7mm dia.

Brass, finished in high gloss chrome.
For putting in rotring technical pens or pencil inserts.

Vailable in nice black box, without pencil insert.

Later version in 1970s was R 532 106, box changed and slight differences with adding red ring.
