Joel,
I have few questions/comments on your message:

I frequently see a number on the arm which does not match
the number on the arc. I always thought that these are some
two different non-related numbers. If I am wrong here,
then very many e-bay sextants are forgeries:-)

SNO-M and SNO-T are equipped with a magnifying glass (microscope).
On my SNO-T, made in 1990, this microscope has (non-electric!)
illumination.
To see this you have to look through the microscope in a very dark room,
after having exposed the sextant to bright light for few minutes.

I suppose this feature may not work on older SNO sextants.


Alex.
