Yes, I checked with Glazer's in Seattle, the 5" rolls that were
in past versions of L-9 are no longer listed in the current
edition.  Guess there wasn't even enough demand to keep them in
teh catalog as non-stocked options.

I can perhaps clarify that a bit, having gone through several of
the 150 foot rolls.  B&H perforations have a very slightly
different shape than Kodak standard perforations.  If you lay
one on top of the other you can see the difference, but I've
never had a 35mm camera that failed to take the bulk HIE, feed
it properly, count frames correctly, etc.  The perforations are
in the right place, and almost identical -- there's probably
more difference between Kodak standard perforations and other
brands of standard 35mm film.  I suspect this might be a problem
in the other direction -- the more precise registration of film
in a movie camera might not accept standard 35mm still film
perforation.  But the bulk stuff does work fine in my Olympus,
Minolta, and Pentax cameras.


As for the earlier comments on the dating of 70mm, I have a roll
waiting for me at Glazer's, and I'll let you know what it says.
But I've used HIE that was past-dated when I bought it, and as
long as it was cold stored the whole time it should be fine
anyway.  I'm currently using bulk HIE that expired two years
ago.  It had expired when I bought it, but had spent its entire
life in a refrigerator, and I've kept it frozen since then; it
gives exposures identical to factory-fresh HIE.
