Maker: Arnold
These strange items, known a “combo” pens, were mainly popular in the 1930s. They saved you the need of having a pocket wide enough for a pen and a pencil, while the only drawbacks were very small supply of ink, a ridiculously short lead, and no eraser. Arnold is one of the better known makers of these objects, and apart from the inherent goofiness of the design, I have to grant that this is a fairly nice little pen. Strong emphasis on the “little”.
