Well, that’s that. The 5611 has faded away with the absorbtion of rotring and Koh-I-Noor Rapidograph Inc. of Bloomsbury, New Jersey into the Sanford company on January 6, 1999.* It appears that Sanford was interested only in rotring and sold the rights to the Rapidograph technical pens and Koh-I-Noor products to Chartpak. Chartpak does not list any Koh-I-Noor thick lead drafting pencils on their website, but they still offer the Rapidomatic. [Update June, 2008] The Chartpak website now links to the Czech Koh-I-Noor website and has no information about the Rapidomatic mechanical pencil or Rapidograph pens.
