My Calipers and Mics are all Starretts. They were issued to me years ago. They are still perfect after 43 years of service. I liked them also for the fact that Starrett Tool owner was the Grand father of Chas. Starrett the Durango Kid of the 1950s B-Westerns. That is for you fellows old enough to recall those days. Chas. Starrett passed away in 1986. Sorry to get off the subject just couldn't help myself. :shake:
