Brand: Eagle Pencil Co.
Made in: USA
Two examples of the Mercantile. the top model appears to be a little earlier example judging by the fluted or crimped ferrule technique which you don't see in later models. I have a similar Eagle Diagraph pencil with the same fluted/crimped ferrule that has a patented date of 1894. Easily a later 1800's to early 1900's model.
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 is today a division of Newell Brands).
