these have been on my project shelf for a year now so it's time for them to go. bought them on astromart thinking i'd make my own eyepieces. also have brass barrels [need some polishing] to go with them someone just needs to put them together. "These are oculars from German and Nato military-design, spotters and binoculars, Excellent contrast , sharpness and edge-correction" $25 shipped for all three or $10 shipped each. glass on all looks good, but have no idea of exact fl, all seem to be 16 to maybe 19mm. all three different. please contact me if you have any questions, realize this ad not too informative. clear skies.
