I shoot APS, 110 and 127 film, they are usually to be saved in 35 mm salvage and the 120 for 127. However l really hope have any "right" salvage for them. Another exception is that l found the PrintFile still selling 3' x 4' salvage can be use for the negative of pack film, maybe just stock, but others like 110, 127 salvages was long gone.
Like you, I use the 35mm pages for my 110 negatives, and 120 pages for my 127 negatives. I don't think anyone manufactures sleeves or pages for those formats anymore.
Sometimes you can find the "right" ones on ebay; either used or "new-old" stock.
