I'm sorry this is a bit vague.
I have some Oly (200µm per revolution, ~ 30mm fine ) part-microscopes.
Some are lurking in the USA. some in the UK
None are the BHTU style rectangular block.
My intention was to make them into stacking rigs with a stepper motors attached, with an Arduino driving them, but life got in the way.
Some have bases, some are the vertical part of the stand. If only the focus mechanism is required, there is no "focus block" to be simply unscrewed. The stands would need cutting up and the section mounting on a flat plate.
What you end up with, is a focus arrangement which is fine enough for sub-micron steps, and backlash free.
Please let me know what you would be interested in, and where you are, because shipping costs would be significant.
Please don't ask for a list with pictures and prices, I don't have a list.
I'm gauging interest at this stage.
As a guide to what's possible, see

Pm's are probably best, though technical questions here would be fine.
