Brand: E. Wolff & Son
Made in: England
Old but goodie! From my understanding of the merger of 3 old British pencil companies into just one under the Royal Sovereign umbrella; an original E. Wolff would be pre 1920's.
E. Wolff & Son was founded in 1796 with a factory in Neasden, London. There were three separate factories at the time: Aurther Johnson, E. Wolff, and Royal Sovereign. Two closed and consolidated to The Royal Sovereign Co. which moved to Wales in 1947. This factory was later taken over and closed in 2009 by Staedtler of Germany.
