how to spot faults and fixtures when buying a second hand microscope, care must be taken because the parts for some are not easiloy found for the older makes and models due to service units keeping hold of them for themseves, and if you do find any they can be very expensive.
A word of advice to anyone buying a microscope it is much better to buy one from those who really know what they are doing, experience for me was gained the hard way, don't you get caught out.
