Mark, that would be very kind. Diameter of units, and depth measured using a
straight edge across and measuring depth at right angle to straight edge would
be ideal. I assume there is very little curvature involved. An option would be
discs of aluminium gently hollowed using a leather sandbag and egg shaped
bossing mallet. Centre hole fitting onto a boss which in turn fits to the FRONT
of my 20mm f3-5 (mk1 )lens.Overall size of stage plate would be useful for
reference. I was going to use clear or frosted 95mm stage plates with a black
card or alloy disc placed centrally - size to be determined experimentally
!!!!I have been looking for mirror housings for years to use with my Leitz
Trinocular microscope. As you say impossible to find at a realistic price.

I have both the PM-LM-20 and PM-LM-38 Lieberkühn reflectors and I can measure
them for you if you want. I also have the matching shade stage plate that goes
in the VST-1 if you need measurements of it as well. I always found the
PM-EL-20 and PM-EL-38 mirror housings easier to use than the Lieberkühn
reflectors but they’re nearly impossible to find now.
