Hello, I purchased a bulk of darkroom equiptment and with it came a 'konica hi-loader' but there are no instructions and google search did not return much. I assume this is a device for bulk loading of film (?). There was also an empty packet of 30m film in this lot of equiptment. I have opened it and saw some film sticking out the end. My equestion is, does anyone know how to operate this device and if so give me some instructions what to do. Is there a way of finding out how much film is left inside? Or is there somewhere I could find instructions to this device. I would not mind making a few rolls of film at home. Thankyou.
