Description
THESE ARE A VERY OLD SET OF OUTSIDE CALIPERS THAT WILL GO OUT TO APPROX. 42" ON AND END MEASUREMENT OF PIPE OR A TREE LOG. CLOSED THE ARMS ARE ABOUT 21 1/2 INCHES. I USED THESE AND OTHERS LIKE FOR LARGE CHURN STYLE WELL DRILLING BITS IN THE 60'S & 70'S. THEY ARE IN VERY USABLE CONDITION. A FEW RUST STAINS I GUESS YOU CALL THEM OR A DISCOLORATION OF THE METAL. NOT RUST.NO MANUFACTURE MARKINGS THAT I SEE. SOME PRINTING WITH A DATE OF 4-1-51, AND A NAME.. I'LL BE LISTING SOME MORE OF THESE IN DIFFERENT SIZES. ANY QUESTIONS PLEASE ASK. THEY ARE NICE AND FIRM SO THEY DON'T MOVE EASILY ONCE SET.
