Brand: Berol Pencil Co.
Made in: USA
I've been looking for this pencil unsharpened for 30 years! Finally got it!! Lightly etched on the reverse: Made by Berol USA. I have seen the Avalanche with Eagle etched into the reverse as well, so I know it exists and I will find one! UPDATE: I now have an Eagle Avalanche 720 and my presumption was right.
The company was originally founded in New York City by the Berolzheimer family, and in 1969 became part of Berol Corporation. Berol was purchased by Empire in 1986, which was purchased by Sanford in 1995 (which has been a division of Newell Rubbermaid since 1992).
