Thank you Mark, Graeme, and Richard:
Luckily this film has been (I believe) stored fairly safely (cool,
dry, dark, sealed) for the past 15 years so I'm fairly hopeful. Well,
maybe not that hopeful about the ASA 3200 Tri-X. <grin>
I may do a little bit more research to better nail down how much
further to extend the processing time (if any), etc.
Regards,
Frank Kurzawa
