Test Scoring 100

The Test Scoring has been made since the 1940's or so. Gallery pick there are four other variations of the Test Scoring. The silver with blue print is pretty cool.  I've also got two variations of the black model.  Interesting, but it appears this pencil started out as yellow, then silver then black and is now being produced in the silver again.  Most other Test Scoring type pencils sport the black polish!  NOTE: The single older yellow model is available for purchase here.  I'm using one and it's wonderful!
