This is a 6-1/2" long x 4" wide x 2-1/4" tall sine plate made by Charles E Strong. This was probably made in the 1950's. It has been cleaned and requalified on the top and bottom, and 5" center on the rolls. This is parallel to .0002" and is 58 to 60 hardness on the Rockwell scale. There is a piece broken out on the front due to the hardness, when it was probably dropped. This sine plate comes with a Hermann Schmidt style clamp system. There are 1/4-20 tapped holes on the top, sides, and ends.
