I’ve seen this same pencil for the last few shows I’ve attended, and most recently in Philadelphia. Its owner doesn’t want his name used:
The Century Pen Company of Whitewater, Wisconsin has been the subject of a couple articles here at the blog. The early metal pencils produced by the company appear to be an original design, and the later 1930s examples look like they may have been made by Eagle.
This one, dating to the mid-1920s, is another National Pen Products creation, made under the 1925 and 1926 Rex Manufacturing Company patents. It took me awhile to place it, because that big cap is more than a little bit distracting:
As this photo indicates, the color of the cap is slightly different than the rest of the trim on the pencil, and it’s unusual to see a ringtop in addition to a side clip – offhand, the only other company I can think of that did that on purpose was LeBeouf. I’m inclined to think, particularly with the mismatch of color, that this is a mismatch, and the cap came from something else.
But from what? It’s an oversized ringtop, which is pretty unusual, and I can’t think of anything else that would have served as the donor for that cap. If you’ve seen that cap on something else, or if you’ve got another Century with this cap on it, please send in a picture!
