Brand: Royal Sovereign Pencil Co.
Made in: England
I think a lot of pencils made in England during WWII were unpainted.
Founded in 1919, the company was formed as a collaboration between two British pencil manufacturers: The House of Arthur Johnson (est. 1803) and E. Wolff & Son (est. 1796). Many Royal Sovereign pencils bare the mark of Arthur Johnson, and if so will have “Made by The Royal Sov.” imprinted on the reverse of the pencil. Royal Sovereign was acquired by Staedtler in the late 1980s.
