Vintage Lufkin Folding tape measure. Patent No. 2,713,206. I believe is in an X46F...or at least that is a number printed on the tip of the tape measure. The exact wording is "X46F Lufkin Red End Extension". Each joint still firmly holds even when it is extended fully. Has its brass 6 inch extension piece at the very front. Other than a few minor chips this tool is indeed in excellent condition. And that is after many manhours of use.
