There are two firms making papers suitable for bromoil that I know of.
I have with some success made bromoil-pictures on the britisk Kentmere
Document Art single-weight and Kentmere Art De Luxe double weight papers.
I have also got hold of the Croatian EMAKS non-supercoated bromoil-paper
("Brom=F6eldruck papier) from the factory of Fotokemika in Zagreb. All these
papers are fibre-based.
I have not ried to make my own paper, I prefer - or rather finds it more
convenient - to use my enlarger.
I believe that Photographer=B4s Formulary in the US stocks Luminos Classic
SW-Art single-weight fibre based paper suitable for the bromoil process.
Good luck.
