Cambo C-240 Roll Film Back

[Nige]

Have uploaded a pic taken with this roll film back and as can be seen the frames overlap. I don't have a manual for it and can't see any adjustment to alter how far it winds on. Any clues?

which from my googling, looks o be the same as the Calumet. Found some instructions for that so i'll see if they make sense Thanks for pointing me in that direction!
