How about a sharp-cut red filter, like a Nikkor...? You can see
through this, and it generally works about as well for IR B&W
daylight photography as the IR filter... (BTW, if you do place
an 87 gel on the film rails, I wonder if it would shift the
film plane about enough to compensate for the IR focus shift...;-}
[though film scratching and dust projections may be a problem])
