Thanks for those links. I took the reflector frame out of the microscope
today and measured it. Looks like the piece of glass needs to be 1" in
diameter and 1/64" thick, though a thinner piece could possibly be used.
According to some articles I've found online, certain metallurgical
microscopes use a plain glass sheet which works by total internal
reflection rather than a semi-silvered mirror. If that's the case with
my microscope, it would make the glass much easier to find. I might even
be able to use a circular glass cover slip.
Then there's the problem of fitting the spring clip over such a thin
piece of glass without breaking it. I figure I should order several
pieces of glass!
Best wishes,

Make up some Tollens reagent (ammoniacal silver nitrate) and use a bit of
glucose solution to set it off.

I'm not too keen on this idea. I'm wanting a working microscope rather
than a time-consuming project.
Best wishes,
