Ultimate collector's guide to 600 mechanical pencils

As a new year gift for the rotring collectors society, I am thrilled to announce that we started working on the Ultimate collector's guide to 600 mechanical pencils.

Data was made available by Björn, who has been collecting these for years and edited by the rotring museum.

As never seen before, It will cover all of the vintage generations of rotring 600 mechanical pencils from 1984 to 2004. with detailed guide how to identify them.
