I have what I believe to be an old Micro-Vu 400 optical comparator
(the label is gone). It has a 20x lens, X-Y-Z table, two Federal
gauges, but is lacking the 10" dia. viewing screen/chart. Anyone out
there have one they want to get rid of, or know where I can get one
cheap? I'm not too interested in buying new. Just a 90dg cross hair
is sufficient, though I'd take anything at this point. My goal is to
eventually sell the thing as I have little use for it.


If you have access to a CAD program you can draw and plot
exactly what you want on mylar drafting film. Make sure the
plotter or printer is calibrated before trusting it to be
accurate. I used to make overlays for a 30" comparator to
inspect the profile of airfoil shaped steam turbine blades
this way.
