Brand: L&C Hardtmuth
It is my understanding that these are about as close to First Edition models as you can find. Both lefties, both are printed in silver and no indication of a Soft, Medium, Hard or Extra Hard was established. A rare find for this otherwise common pencil.
L&C Hardtmuth was formed in 1790 by Josef Hardtmuth in Vienna, Austria. In 1802 he patented the first pencil lead made from a combination of clay and graphite, and in 1848 the company was moved to the city of Budweis in what is today the Czech Republic. In 1888 they introduced the KOH-I-NOOR pencil, named after the largest known diamond in the world at that time. Today the company operates under the name KOH-I-NOOR HARDTMUTH.
