24 inch starrett digital caliper. Paid over 1100 new. Very accurate. I no longer need it as i do not work in mills anymore. The dove tail box is a 1956 model 97 starett. Basically an early version of the 98. It's a 12 inch. 100 on it. The f clamp holder hangs on the handle of a gangbox. I built it out stainless steel and it works great for being able to find your clamps when you need them instead of digging into the bottom of your gangbox. $60.00 Don't need help selling it. Contact me at nine 1 eight five 3 zero two seven 1 five. Also have several more precision tools. and maybe a road gangbox that's fully equipped with organization.
