Sokkisha-Tokyo Mitutoyo Paralax Bar  0-25mm in Lietz Wood Box Photogrammetry Tool. Nice Sokkisha photogrammetry tool used at a college that I purchased at an auction of drafting and surveying items in Ohio. Good shape with minor wear from use in a teaching setting. Use to take measurements off of stereo photographs for surveying, highway construction, etc. Estimated weight about 2 lbs well packed. Thanks!
