B66-51 PENCIL SHARPENER. Chelsea. Technically known as the "Standard" pencil sharpener but usually referred to as the Chelsea after its manufacturer, this very rare sharpener, sold only for a few years at the dawn of the last century, used a circular sheet of sandpaper rather than blades. Includes the sandpaper disk and is complete and working, with 90% original silver paint and "Pat Apd For" cast into side. One of these in the original box set the world's record for an antique pencil sharpener and was sold at Brown's 24th auction. From the collection of Jim and Christa Schoenky. Good+ 500-1000
