This microscope has been fully inspected and bench-tested. The optics are clear, providing sharp image resolution across all three M-series metallurgical objectives. Mechanically, the coarse and fine focus adjustments travel smoothly, the triple nosepiece detents lock into center cleanly, and the integrated mechanical X-Y stage tracks perfectly across both axes. The horizontal illumination lamp assembly is operational, and the physical housing shows only minimal signs of light, standard laboratory use. Ready for professional service or collection.
