    The detail in this illustration is amazing, the time it must of took to do this all manually, (pen & pencil)

    then this has to be reviewed by someone in the patent office who is knowledgeable. No wonder it takes so long to get a patent.

    I would have liked to see the patent agents face when this was presented. What a contraption!
