Thanks for the comments.

I would not be surprised if necessity is being the mother of invention once more, if it is true that use of paper negatives is increasing: sheet film is madly expensive!

(The usual cheaper standby for US-based LF photographers - X-ray film - is equally if not more expensive than normal pictorial film in the UK, and while Arista Ortho Litho can be imported, it nearly doubles in price thereby and of course has its own shortcomings)

Thanks also, by the way, Ned, for your kind & encouraging comments at Ipernity
