Offering this Vintage Disston Carlson 10 foot Engineer's Tape Measure Model No. 3210 in nice pre owned shape as shown. Back is embossed H. K. Porter Co. which was a Railroad Locomotive manufacturer in the Pittsburgh area. From a family estate and the family member worked there in the late 1940's but I'm unsure if that was how it was obtained. Also has a faded name written on back. Does not lock out and you slide back in by hand. Great vintage find ! Please zoom on pics as they are part of the description and ask any questions before bidding/buying.
