Wrong, much is on Estar and similar base.

I've seen too much good professional film from the Fifties to be
willing to blame the film itself ...the problem's bad processing
and/or storage. "Trade" processing means nothing.

No, it's cheap. Start with proper sleeves (never anything by Negafile)
and dark storage. Mundane glassine sleeves, such as Savage, Agfa, and
Hasselblad have done very well, despite not being "archival." Time to
replace them now, but give them their credit.

Yes, of course, but I suspect few of us are having your film problems.
