Test Scoring 100

Old and new model.  The Test Scoring has been made since the 1940's or so.  Top silver is older while the bottom silver model is being made today.  Also in the gallery pick there are three other variations of the Test Scoring. The silver with blue type is pretty cool.  I've also got two variations of the black model.  Interesting, but it appears this pencil started out as silver then turned black and is now being produced in the silver again.  Most other Test Scoring type pencil do use the black polish.
