Description is exactly
Condition:
Cosmetically: There has significant crazing (without cracking) on both sides of the substage plano-concave mirror and is missing most of the lacquer. A plinth has been custom fitted as a replacement.
Optically: The lenses are clear and functional.
Mechanically: The coarse adjustment focusing rack and pinion mechanism are intact with all teeth present; however, it does move somewhat loosely but does not spontaneously drift. The mechanical stage is also intact, moving well if a little loosely, but again without drift.
