Chicago Automatic Pencil Sharpener #2

My grandmother-in-law is 101 (soon to be 102) and stopped driving at around the age of 99. When she moved in with my in-laws, I was given a workbench that used to belong to her late husband. The bench had an antique pencil sharpener attached to it. This is the second antique pencil sharpener I own. You can read about the first one HERE. It does a great job considering the age. The insides could use a bit of cleaning to say the least, but it is interesting to see the various colors on the blades. I have no idea what the age of this pencil sharpener is. If you know, please contact me. I would greatly appreciate it. On to the photos!
