I have the display assemblies from a Beckman Scintillation counter -- they
are amazing.  Each one is about 1 1/2 x 2 1/4 x 5 (inches) and has twelve
miniature bayonet pilot lamps at the back (currently #44, which is a 6.3v
bulb).  It has an optical system with four lenses for each lamp, and it
projects any of twelve images onto a frosted screen at the front.  The
images are on a convex plastic film/stencil placed immediately in front of
the third lens-plate from the lamps.  The modules look as though they cost
$100 each...

Any interest?  You could fake the curvature with individual little flat
pieces -- but the image cells are only about 3/4 cm -- not inch --
square.  There are also positions provided for placing little colored
filters in the beam.  The "ground glass" screen is a long strip that passes
in front of the whole assembly, but I could cut pieces from it.

I really hate to ditch these things, but I don't have a use for them myself
(I might keep one).  Talk to me -- they're going on the street Monday night.
