Pen Model: Diamond Point
Diamond Point was one of many minor New York City manufacturers of decent quality fountain pens that reached their apex in the 1920s, only to lose their significance and production quality during the Depression. As noted by Richard Binder and others, management change in or around 1920 renamed the firm to the New Diamond Point Pen Company, and their quality was improved. These are often very substantial and handsome pens, both before 1920 when they were made of ebonite, and after, when they were predominantly made of celluloid.
