Teledeltos paper is still on the market.  See here, for example:
-- https://www.betterequipped.co.uk/teledeltos-conductive-paper-prd1516-pack-of-10-sheetsp-1262

Of course, it's not sold for Deskfax use.  After WU developed the Deskfax, people found other uses for the paper for analog computation of electrostatic and magnetostatic fields.  Those are messy enough that even today, it's as easy to take a sheet of teledeltos paper and stick electrodes to it than it is to do the field computations on a computer.
