Dialer Pencils/Autopoint/Mark Sense

[Chuck Naill]

My father worked for the telephone company. I do remember seeing these at his office. Autopoint made them, perhaps other makers as well. Mark Sense is whole other topic and related to IMB punch card technology. https://en.wikipedia.org/wiki/Mark_sense

This is the only red one I have seen. Black and green are common. Usually stamped "Bell Property". Many Esterbrook FP's were stamped "Bell Property" as well.
