I have a question to which I couldn't find a fitting sub-board, so I thought I'd take the virginity of this one instead to catch your attention.

I'm trying to hunt down one Robert Firth who has published a series of most interesting research notes regarding the VM back in the nineties, but all I could find was a mirror hosted by Jorge Stolfi of notes compiled by Jim Reeds. (https://www.ic.unicamp.br/~stolfi/voynich/mirror/firth/)
Does anybody know if Robert is still about, pursuing the VM?
TIA,
Cheers,
