Joe, I doubt that the microscope will sell for $10 to $20 for an E. Leitz,
there are a lot of collectors out there and they would love it. However if
you can get it do! The 2" piece you describe is the illuminator shaft. The
light source for this microscope would go in there. It is aparently
missing. The 100X is an oil lens. Its rare to find a bio 100 that isn't.
The thread diameter for all microscopes of that time is identical but the
compensation for various optical things can either be in the objective or
eyepiece. Some makers use the eyepiece and some use the objective. Thats
why its always bad to put the wrong objectives on a microscope. For a
usable microscope look around, you might find a better instrument.

Good luck.
