Here is a nearly complete set of University Optic Orthoscopics that I pieced together over time. All UO branded EPs are perfect / like new, no setscrew marks and come as pictured. The 12.5 is a Kokusai Kohki brand (same as UO) and is in excellent condition, no setscrew marks.
Price for the whole set 4,5,6,7,12.5 and 18mm is 210.00 shipped.
Only reason I'm selling these is to help finance monocentrics.
