    So my girlie and I are thinking of spooling up some 35mm bulk film I have laying around onto 127 spools, but we don't have any backing paper. Does anyone know what the specs for that are?

    i.e., how big the paper is, what the distance is from film start to paper start, where the start markings are, where the numbers are etc.

    Alternatively, does anyone have any spare 127 backing paper they'd care to send our way?

    I do know that 127 is still for sale from Impex, but it's expensive, and I have 4 spools of expired Ilford HP5+ taking up space in the fridge, and it's partly for the tinker value anyway...

    thx in advance for any pointers!

    The paper is 108cm long (but you can put more or less leader if you wish).
    I'll start with the double-arrow registration marks that you line up before closing the camera back:

    These are minimums so you don't get overlapping frames.
    Double Arrow 0 cm
    film start 14cm
    "1" 18.5cm
    "2" 23cm
    "3" 28cm
    "4" 33cm
    "5" 37.5cm
    etc
    "12" 70.5cm
    end mark 77.5cm

    Since you are doing it yourself, you can go every 5cm if you wish, to give yourself a safety margin between frames.
    Of course, you can go longer if you don't use backing paper. Just cover the window with electrical tape & load/unload in darkroom.

    You may have a look at www.macodirekt.de . They are much cheaper with fresh Efke R100 in 127.
    They also have still some color film in 127 (expired).
