I have a box of Lupex (and coincidentally some late Lodima) I've been meaning to try out (I never used Azo) but haven't had the time. It's an idle curiosity for me, admittedly mostly in the context of print developer variation. I think it's just steeped in a specific tradition - MAS and adherents were/are hard core trying to do things the way EW did, that sort of thing. As far as I remember MAS would only use Super-XX, D-1/ABC, Amidol with water bath etc. so you know where he was coming from.
I'm hoping I can do something useful with the paper.

50+ years ago, Azo (and equivalents like Lupex) generally had a more favourable curve shape and MTF character than many common papers on the market at the time (e.g. Kodabromide) that were being iterated through revisions to remove some environmentally problematic components that inherently aren't required in a chloride paper - technology caught up with it (and essentially made variants on the idea not just enlarging speed, but the basis of modern colour papers), but not with those who made a living out of selling doctrine in weekend workshops.
