Description: Overstock from my lab. Viewthrough is clean. It includes special mount for Reichert microscope (it can be used in other microscopes if you remove it, as in 5th picture).
Issues: some marks in body. Bottom has very small coating marks (no scratches), see 3rd picture. Negligible in practice.
