: The 9th &10th edtions of Graphic Graflex Photography talke about how to do it and what its applications are, so I have to assume all pacemakers and Anniversaries would handle it.
: Pre-Anns and before may need to wrap the bellows in Aluminum foil, like NASA did the LM.
: All modern film holders can handle IR film. The standard is if the notch on the darkslide has 5 dimples or pimples it's IR safe, 3 dimples and its as usefull as a double punched ballot.
