Autopoint is an interesting company to mechanical pencil collectors because, unlike many other pencil makers, they weren't particularly obsessed with pens. Yes, they made them, but it was pencils that were the mainstay of the company.
This black, ten-sided, nose-drive pencil has a ribbed metal cap covering the eraser. At 5.75 inches, it is long and slim, too, with a plain, straight clip. Sadly, the clip's chrome finish is in poor condition. Under the cap is where to look for the Autopoint mark: "Autopoint" in italic script, "PAT AND PATS PENDING, MADE IN USA, CHICAGO."
It's safe to date this pencil to after 1938, when 0.9 mm lead was introduced as "thin lead." It probably wasn't much after that introduction that this pencil was made, since a notice has been inscribed on the side of the pencil that it is "FOR Real Thin LEAD." The words Real Thin are in the font Realite used on their pencil clips. Realite owned the Autopoint company from 1923 on, calling the merged company Autopoint Products Company.
In spite of its slightly tatty condition, I like this unassuming pencil. It makes me want to look at Autopoints more often.
