I just got an old Daylight bulk film winder at a local auction today in a box with some very old darkroom equipment. I'm trying to find instructions on how to use it. I haven't opened it yet. I think there may be film in it. There was no instruction book but only a Tri-X bulk film paper instruction. I found similar ones for sale on ebay for less than $10 US but none with instructions. Can anyone help? Thanks in advance-Ken
