Rare 6” Precision Square. Made By Mauser In Germany! In very good condition.

I am a retired toolmaker and this has been in my Gerstner box for over 30 years. It has never been mistreated and it remains a very accurate tool. And it makes a great conversation piece as well! I don’t know exactly how old it is but it was old when I got it too. Will even serve as a great collector’s item.
