Vintage Pencil Sharpener Restoration & Modification --- AF invention

For a long time I've wanted to restore one of these old hand cranked pencil sharpeners. Restoring mechanical items is always so interesting and this type of vintage sharpener are beautiful. The sharpener was very rusty and it didn't sharpen pens very well so it was in need of a restoration. This pencil sharpener is made by Boston but I'm not sure what year it is. Possibly from the 1940's.
