Yes if you need the numbers. No if you have a gray Rollei or a Sawyer that indexes itself.
With everything but the Rolleiflex you have to measure the start line difference.
And it is too long by about 6.5 inches.
EDIT: A scheme that I have been working on, with no time to execute it properly, is to make a jig that lets me cut the excess length into two 2.25x3.25 sheets, then slit the remainder into both a roll of 127 and a roll for reloading a 16mm Minolta cartridge. Very little waste. I'm going to get around to all these plans "one of these days" if I don't die first.
I keep telling folks that if I win the lottery next week I still have to set my alarm clock. I've got more outstanding projects on the table than I can finish in my life even if I never had to spend another day earning a living.
