I think
@Kino mentioned in his former workplace they processed a lot of this material as well. Maybe he can chime in.
It's a Panchro Dupe Negative stock for copying Fine Grain Master Positives and (with gamma correction) existing release prints.
It will be ungodly slow as a camera original, but should be very fine grained. We processed it at .50, .60 and .70 relative gammas in D96, but it should work just fine in any MQ type developer with fine tuning.
Tends toward a long, flat curve with fairly sharp breaks on toe and shoulder (at least in Motion Picture Printers with Halogen light sources) so take that into account.
Hope this helps.
BTW; D96 is, more or less, a modified version of D76 with more buffering to keep the HQ from running wild as it ages and PH increases. D76 should give nearly identical results.
Dont' be afraid to give it good agitation if you want better contrast...
