How translucent or opaque is the material? I am thinking about maybe tail
light repair tape used on cars. It is red, thin, fairly opaque in appearance
(but allows the light through)and is self adhesive. It can be purchased at
just about any auto parts store. May not be exactly what you are looking for
but may work out well anyway. Then again it may be too opaque.
Just a thought,

As I
restore this ET-3400, I am curious if anyone knows what
kind of filter material Heathkit provided that sticks to the
TIL312 7-segment displays?
Two ideas come to mind - lighting gels, used in stage lighting, and
Kodak makes lens filter gels in a huge range of colors. Both these items
will appear to be colored sheets of plastic. From this and a couple of off-line suggestions, I
guess I should be
more precise in my description of the material in question. The
ET-3400 has no bezel around the TIL-312 displays. The red filter
material provided by Heathkit was pre-cut to the exact size of the
face of each display, and sticks on by its own adhesive. It seems to
be quite soft (vinyl-like as opposed to mylar-like) and quite thin -
much thinner than scotch tape.
I'm sure I can find some sort of red non-adhesive plastic, but I was
really hoping to find the same sort of material they used so the
displays match.
Thanks,
