How well does it work with a thin (say, one back from Kodak) cardboard
mount?  Does it "lean" over in the slot so there is a focus imperfection
top to bottom or is there something in it that keeps it pushed to one
side (and straight)?  I don't recall from when I last saw one.

P.S. - It's a magnificient viewer, I love looking at it whenever
       I have had an opportunity.  Someday.... after the RBT camera.  :-)
