Hello Group:

I am interested in tracking down info on an old source.  It is an AN/UDM-1A,
referred to as a Cs camera and used to perform calibrations of survey meters.
What I would like to find is who made these devices and who supplied the sources
for these devices.  If anyone has some knowledge about these sources
they can contact
me off-line at
