John -

Thanks for the explanation on the anti-lightpipe dye.  I've never heard
of it.  If you do come across the source for the information please post
it, as I'd be very interested in reading more.

As far as the felt trap is concerned, I got that information from Walter
Horylev, one of Kodak's IR guys (he still gives IR workshops in
Rochester).  We must be using different large format holders, as mine
don't have felt anywhere.

An aside:  The small series of notches on the dark slide (usually there
are five) indicate that the slide is IR-proof.
