I bought some 120 B/W film from Ultrafine last year that is most likely Lucky. I believe Lucky also makes B/W paper. I have some of the Ultrafine paper, also bought last year. Comparing it to the Arista EDU Ultra VC RC, the texture is a bit different, it responds to contrast filtration differently, and the Ultrafine paper has a slight tendency to curl away from the emulsion side. This is the opposite of the Freestyle/Foma paper.
I think there is a distinct possibility the Ultrafine paper is Lucky, or Chinese made at least. There is no country of origin listed for either the Ultrafine 120 film or the Ultrafine paper.
