Rotring Compass Lead Insert 538 232

New old stock, from the 1980s.

The lead can be altered by either depressing or unscrewing the top plunger which opens the clutch to a required position.

Rotring developed the unit to attach to their Pump Technical Pen Compass to allow the user to easily switch between the technical pen and the pencil.

Made for a tight fit into these attachments which are not included in this sale.
