I want to make up some spacers to fit a 120 film into a 616 camera. I have a 616 spool but I left it at home and I am at work at the moment. If you have a 616 spool, I would appreciate it if you could measure the overall length and less importantly, the diameter. I am guessing that the length will be about 68mm/2.69" and the diameter will be about 23.5mm/0.93" but would like some confirmation. Thanks, Steve.
