I've just seen the mention here of this release : https://www.discogs.com/Felt-1984/release/7625425
I know that Lawrence is against to output demos or any bonus so I don't think they could be related to any future or ancient repress project.
I've done some basic research and it seems that Arkain Filloux is in fact an Italian outfit (the Belgian address seems to be fake). I remember that back in the 80's and the 90's mots of the bootlegs labels were Italians. I've found very little comments on the sound quality of their releases but they were positive. I guess that the Felt LP is new or even not released yet because i didn’t find any sale on Discogs or Ebay. Maybe it’s also because they were shutdown. They’ve done bootlegs from some high profils artists like the Velvet Underground or the Smiths and I guess that their big labels coud have filed some lawsuit, or, at least, threaten to do.
I've never heard of these Felt demos, were they available before on mp3 sharing platform ?
